a 0.150 kg baseball traveling with a horizontal speed of 4.70 m/s is hit by a bat and then moves with a speed of 32.5 m/s in the opposite direction. what is the change in the ball's momentum?

The torque would be directly proportional with the distance in the torque-lever length connection.

Torque is defined as an action that causes something to rotate. To spin an object, a torque is necessary, just as a force is desired to propel an object in a straight line. Torque is produced by force, it is also affected by the location of the force and indeed the point that occurs when object rotates.

Force as well as lever arm aren't always parallel. Trigonometry is necessary to compute the length of something like the lever arm when the force as well as lever arm are really not perpendicular.

The applied force originates orthogonal to the rotating object's surface. Whenever this force occurs at an angle with the plane of something like the object, the sine function must be used to calculate the perpendicular force.

An object is moving in simple harmonic motion. Its current position is 0.6 m to the right of its equilibrium. The object will move 0.24 m further to the right before it stops momentarily and then starts to move back to the left.

The position function of  simple harmonic motion can be modeled by:

x(t) = A sin (ωt)

Where:

A = amplitude

ω = angular frequency

t = time

Amplitude is the farthest displacement before the object move back to the left or right.

Substitute x(t) = 0.6

0.6  = A sin (ωt)

Take the derivative:

v(t) =  Aω cos(ωt)

Take the derivative again:

a(t) = v(t)' = -Aω² sin(ωt)

-8.40 = - Aω² sin(ωt)

x(t) / a(t) = A sin(ωt) / ( -Aω² sin(ωt))

0.60 / (-8.40)  = -1 / ω²

ω² = 8.4/0.6 = 14

ω = 3.74 rad/s  

x(t) / v(t) = A sin(ωt) / Aω cos(ωt)

0.6 / 2.2 = tan(3.74t) /3.74

tan(3.74t) = 1.02

3.74 t = 0.795

t = 0.212 s

x(0.212) = A sin(3.74 x 0.212)

A = 0.84 m

The farthest position from the equilibrium is 0.84 m, hence the object will move 0.84 - 0.6 = 0.24 meters farther before it moves back to the left.

Using  conservation of linear momentum, the final velocity is 7.2 ms⁻¹.

The conservation of linear momentum states that the momentum of a system of bodies remains constant if the net external force acting on the system is zero. We must keep in mind that the system's momentum, not the momentum of the individual particles, is conserved. According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.

P = mv is the equation for linear momentum. Conservation of momentum refers to the fact that the overall amount of momentum remains constant.

As per conservation of linear momentum,

At the lowest position of a simple pendulum, the tangential acceleration is zero. Acceleration is the measure of a change in velocity. Acceleration frequently, but not always, denotes a shift in speed.

In mechanics, acceleration refers to the rate at which an object's velocity with respect to time varies. Acceleration is a vector quantity (in that they have magnitude and direction). The direction of an object's acceleration is determined by the direction of the net force that is applied to it. According to Newton's Second Law, the object's mass, which changes based on the materials it is built of, and the net balance of all external forces acting on it both contribute to an object's acceleration. The mass of an item has an inverse relationship with the magnitude of its acceleration.

Answer:

Approximately [tex]11\; {\rm m}[/tex], assuming that gravitational acceleration is [tex]g = 9.81\; {\rm m\cdot s^{-2}}[/tex] and that air resistance is negligible.

Explanation:

The question is asking for the vertical displacement, [tex]x_{y}[/tex].

Under the assumptions, acceleration in the vertical direction would be [tex]a_{y} = -g = (-9.81)\; {\rm m\cdot s^{-2}}[/tex].

Since the projectile is launched horizontally, initial vertical velocity would be zero: [tex]u_{y} = 0\; {\rm m\cdot s^{-1}}[/tex].

It is given that the projectile is in this motion for [tex]t = 2.2\; {\rm s}[/tex]. Apply the SUVAT equation [tex]x = (1/2)\, a\, t^{2} + u\, t[/tex] and solve for the vertical displacement:

[tex]\begin{aligned}x_{y} &= \frac{1}{2}\, a_{y}\, t^{2} + u_{y}\, t \\ &= \frac{1}{2}\, ((-9.81)\; {\rm m\cdot s^{-2}})\, (2.2\; {\rm s})^{2} + (0\; {\rm m\cdot s^{-1}})\, (2.2\; {\rm s}) \\ &= \frac{(-9.81)\, (2.2)^{2}}{2}\; {\rm m} \\ &\approx (-11)\; {\rm m} \end{aligned}[/tex].

Note that the value of vertical displacement is negative since the projectile landed below where it was launched. The height of this cliff would be approximately [tex]11\; {\rm m}[/tex].

In a pendulum, the acceleration is at the greatest rate at the point of greatest displacement from the equilibrium or the point of highest amplitude.

A pendulum is a weight suspended from a fixed point that swings back and forth due to the force of gravity. The most common form of a pendulum is a weight, or bob, hanging from a cord or rod. When the pendulum is given an initial push, it will continue to swing back and forth due to the force of gravity acting on the bob. The motion of a pendulum is known as oscillation.

At the highest point of the swing, the velocity of the pendulum is zero and the acceleration is at its maximum as the pendulum changes direction. At this point, the acceleration is directed towards the center of oscillation and is directed towards the equilibrium position. As the pendulum swings back and forth, the acceleration decreases as the velocity of the pendulum increases and reaches zero again at the highest point of the swing.

It's also worth noting that, the acceleration of a pendulum is not constant, but it is changing as the pendulum swings, and it's greatest at the point of the highest amplitude and it is directed towards the center of oscillation.

Therefore, the acceleration is at the greatest rate at the point of highest amplitude.

Answer:

Explanation:

The rate of breathing is affected by the environment's pressure and temperature. The pressure and temperature are lower at greater altitudes. As a result, the man's lungs will have to work harder to breath the same volume of air. We may use the following calculation to compute the new rate of breathing:

(Pressure1 x Temperature1) x Rate of breathing1 = (Pressure2 x Temperature2) x Rate of breathing1

Where Pressure1, Temperature1, and Rate of breathing1 are the pressure, temperature, and rate of breathing at sea level (760mm Hg, 18 degrees Degrees c, and 16 breaths per minute), and Pressure2, Temperature2 are the pressure and temperature at the mountain top (760mm Hg, 18 degrees Celsius, and 16 breaths per minute) (240mm Hg, 5 degrees C)

Plugging in the values, we get:

Rate of breathing = (760 x 18) / (240 x 5) x 16

Rate of breathing = 4 x 16

Rate of breathing = 64 breaths per minute

So the man's rate of breathing at the mountain top would be 64 breaths per minute. This means that his lungs would have to work 4 times harder to inhale the same mass of air as at sea level due to the lower pressure and temperature at the mountain top.

ATP and NADPH serve as the chemical fuel for the light independent processes, often referred to as the Calvin cycle.

Adenosine triphosphate, also known as ATP, is a highly energetic molecule that both stores and releases energy. It is created by the process of photophosphorylation during the light-dependent activities of photosynthesis. Another high-energy molecule formed during the light-dependent processes is NADPH, or nicotinamide adenine dinucleotide phosphate. This happens as a result of non-cyclic electron transport.
