A lead ball at `25^@`C is dropped from a height of 2 km. It is heated due to air resistance and it is assumed that all of its kinetic energy is used in increasing the temperature of ball. Find the final temperature of the ball.

A lead ball at 30^@C is dropped from a height of 6.2km . The ball is heated due to the air resestance and it completely melts just before reaching the ground. The molten substance falls slowly on the ground. Calculate the latent heat of fusion of lead. Specific heat capacity of lead =126 J//Kg-^(@)C and the melting point of lead =330^@C . Assume that any mechanical energy lost is used to heat the ball.

A lead ball at 30^(@)C is dropped from a height h. The ball is heated due to the air resistance and it completely melts just before reaching the ground, The molten substance falls slowly on the ground. Latent heat of fusion of lead is 22200 Jk//g . Specific heat capacity of lead =126J//kg-^(@)C and melting point of lead =330^(@)C , Assume that all mechanical energy lost is used to heat the ball. Find the value of h in km ? ("Use" g=10 m//s2)

A ball is dropped from a height of 20 cm. The ball rebounds to a height of 10 cm. What is loss of energy?

A 2 kg ball is dropped from a height of 1. Find its kinetic energy just before hitting ground.

An inelastic ball is dropped from a height of 100 m.Due to earth 20 % of its energy is lost.to what height will the ball rise?

An inelastic ball is dropped from a height of 100 m. Due to earth 20% of its energy is lost. To what height the ball will rise ?

A ball is dropped from a height of 20m. it rebounds to a height on 10m. Calculate the loss of energy of the ball

A ball is dropped on a floor from a height of 2.0m After the collision it rises up to a height of 1.5m . Assume that 40% of the mechanical energy lost goes as thermal energy into the ball. Calculate the rise in the temperature of the ball in the collision heat capacity of the ball is 800J K^(-1)
