A body of mass 5 kg falls from a height of 20 metres on the ground and it rebounds to a height of 0.2 m. If the loss in potential energy is used up by the body, then what will be the temperature rise? `("specific heat of material = 0.09 cal gm"^(–1@)"C"^(–1))`

A body of mass 0.2 kg falls from a height of 10 m to a height of 6 m above the ground. Find the loss in potential energy taking place in the body. [g=10ms^(-2)]

A body of mass 5kg falls from a height of 5m. How much energy does it possess at any instant?

A rubber ball of mass 0.05 kg falls from a height of 1 m and rebounds to a height of 0.5 m. Find the average force when their contact was 0.1 sec.

A steel ball of mass 0.1 kg falls freely from a height of 10 m and bounces to a height of 5.4 m from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in its temperature is (specific heat of steel =460 K//kg^(@)//C,g=10 m//s^(2) )

A steel ball of mass 0.1 kg falls freely from a height of 10 m and bounces to a height of 5.4 m from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in its temperature is (specific heat of steel =460 K//kg^(@)//C,g=10 m//s^(2) )

A brass sphere of mass 0.2 kg falls freely from a height of 24m and bounces to a height of 8m from the ground. If the dissipated energy in this process is dosorbed by the sphere the rise in its temperature is (specific heat of brass =360 J " kg"^(-1)k^(-1) and g=10ms^(-2) ).
