The magnitude of the acceleration of the block is 1.78m/s².

The coefficient of kinetic friction between the block and the ramp is  0.368.

The resistive force of friction (Fr), which pushes the objects together, is divided by the normal or perpendicular force (N), which pushes them apart, to produce the coefficient of friction (fr), which is a numerical value. The following formula represents it: fr = Fr/N.

Given,

m=3.00kg, θ=30° ,

x= 2.00m, t=1.50s.

[tex]X_{f} = v_{i} t[/tex] + 1/2at²

solving,

a = 2([tex]X_{f}[/tex]-[tex]v_{i} t[/tex])/t²

a = 2(2-0)/(1.5)²

a = 1.78m/s².

We have neither a burrowing-in nor a taking-off action when Newton's law is applied in the y direction, which is perpendicular to the inclination. The y component of acceleration is then equal to zero:

Cost estimated is ₹[19/4]y/-.

Given :- Power=3kW  , Time=1hr 35min

Now to convert this time completely into hours following steps can be adopted:- 1 min =1/60 hour,       so 35min =35/60 hour

35min= 35/60 =7/12 hour

So total computed time = 1hr + [7/12]hr

computed time =19/12hr

Now since in the question there is no mention about cost , so let the cost be ₹y/unit.

Mathematically , Energy is the product of power and time , i.e.

E= Power x Computed time = 3 x 19/12 = 19/4 units.

Now the energy estimated is 19/4 units whose cost equivalent will be ₹[19/4]y/- , as cost of one unit energy  is ₹y/- so cost of 19/4 energy units will be ₹[19/4]y/-.

it will have constant friction,  or slowing, as it slides along the ice.

It  would be half of (1/2) acceleration due to gravity on an object near the surface of that planet compare to our g.

Gravity on the planet (g') = [tex]\frac{GM}{R'^{2} }[/tex] = G(ρx [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]R^{3}[/tex])/[tex]R'^{2}[/tex]

Where R' is the radius of the planet.

g' = [tex]\frac{4}{3}[/tex][tex]\frac{\pi GPR'}{1}[/tex]

gravity on the Earth (g) = G[tex]M_{E}[/tex]/RE

                                      = G([tex]\frac{P 4/3\pi R_{E} ^{3} }{R_{E^{2} } }[/tex])

                                  g  =  4/3 [tex]\pi[/tex]GP[tex]R_{E}[/tex]

Now, g'/g = R'/[tex]R_{E}[/tex] =  [tex]R_{E} 2[/tex]/[tex]R_{E}[/tex] = 1/2

              g' = 1/2

it would be half of g.
