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 10m an bounces to a height of 5.4m from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in ots temperature is (Specific heat of steel= 460 JKg^(-1)K^(-1)) (g=10ms^(-2)) .

A brass sphere of mass 0.2kg falls freely from a height of 20m and bounces to a height of 8m from the ground. If the dissipated energy in this process is absorbed by the sphere the eise in its temperature is (specific heat of brass =360 J kg^(-1)K^(-1) , g=10ms^(-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) ).

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 metal ball of mass 5 kg falls from a height of 490 m. How much time will it take to reach the ground ?
