In 11.1d, what would the velocity be 15 s after the start if the acceleration were maintained?
What is the velocity of an object accelerating at 5.0 m/s² after 15 s having started from
rest?
Answer:In physics, the velocity of an object under constant acceleration can be calculated using the following formula:
v = vₒ + at
where vₒ is the initial velocity (assumed to be zero if the object is starting from rest), a is the acceleration, and t is the time elapsed.
If the acceleration were maintained:
v = vₒ + at
v = 0 + (5 m/s²) * (15 s) = 75 m/s
So, the velocity would be 75 m/s after 15 seconds if the acceleration were maintained.
If the object is starting from rest:
v = vₒ + at
v = 0 + (5 m/s²) * (15 s) = 75 m/s
So, the velocity of an object accelerating at 5.0 m/s² after 15 s, having started from rest, would be 75 m/s.

a metal conducting sphere of radius r holds a total charge q. what is the surface charge density, , on the outer surface of the conducting sphere?
The surface charge density of the metal conducting sphere on the outside is zero.
Conductive hollow spheres are positively charged with a +q Coulomb charge. If a sphere has the same density across its surface, the +q charge will be evenly distributed across the surface. So the whole system is a symmetrical system. Charge density depends on the amount of charge and the surface area of the conductor or the size of the conductor. A conductor with an uneven surface has different surface areas at different locations on its surface. As a result, the surface charge density varies from point to point on the surface.

The time by which the two cars initially 2.50km apart and moving towards each other meet is 194 seconds.
The two cars are initially 2.50km apart. So the distance between the two cars,d= 2.50km. The speed of car 1 is v₁=7.50 m/sec. The speed of car 2 is v₂=5.40 m/sec. Let t be the time at which the two cars meet. Then at time t, the distance traveled by the two cars will be equal to the distance between them initially.
So, the distance d₁ traveled by car1 is 7.50×t m. The distance d₂ traveled by car 2 is 5.40×t m. Now d₁+d₂=2500, 7.5×t+5.4×t=2500, 12.9×t=2500, t= 2500/12.9, t=193.8 secs. So the time by which the two cars meet is 194 secs.

a rubber balloon is blown up and the end tied. is the pressure inside the balloon greater than, less than, or equal to the ambient atmospheric pressure?
The pressure inside the rubber balloon is greater than the ambient atmospheric pressure.
The pressure inside the rubber balloon is greater than the ambient atmospheric pressure because when the balloon is blown up, the person blowing the balloon is compressing the air inside the balloon. According to gas laws, when a gas is compressed, the pressure inside the container increases. When the end of the balloon is tied, this compressed air is confined within the balloon, which causes the balloon to expand.
When air is compressed, the particles of the air molecules move closer together and collide more frequently. This increases the force of the collisions and creates an increase in pressure. This is why the pressure inside the rubber balloon is greater than the ambient atmospheric pressure.
In summary, when the rubber balloon is blown up, the air inside the balloon is compressed and the pressure inside the balloon is greater than the surrounding ambient atmospheric pressure.

a 2 kg bowling ball travelling at 4 m/s hits a stone wall and stops. what is the impulse acting on the bowling ball? kg*m/s
The impulse acting on the bowling ball is - 6kg m/s
An object's impulse can be defined as the amount by which its momentum shifts as a direct result of a force being applied to it for a certain amount of time. To calculate impulse, we can use this following formula:
Impulse = Δp = p final – p initial
Where,
Δp = the change in momentum
Pfinal = the final momentum
Pinitial =the initial momentum
Hence, the impulse:
Δp = pf – pi
Δp = m x vf – m x vi
In this case, we are given that:
the mass of the bowling ball (m) = 2 kg
the velocity before it hits the stone (vi) = 4 m/s
the velocity after it hits the stone (vf) = 0 m/s (since the ball stopped)
So,
Δp = (2.0 kg) (0. m/s) – (2.0 kg) (4.0 m/s)
