A lead bullet of mass 50g moving with a velocity of 100ms^(-1) strikes a target. If 40% of the heat produced is retained by the bullet, calculate the rise in its temperature. Specific heat of lead = 0.03 cal g^(-1)K^(-1) and J = 4.2 J cal^(-1)

A lead bullet of 10g travelling at 300m//s strikes against a block of wood and comes to rest. Assuming 50% heat is absorbed by the bullet, the increase in its temperature is (sp-heat of lead is 150J//Kg-K )

A ball moving with a velocity v strikes a wall moving toward the wall with a velocity u. An elastic impact occurs. Determine the velocity of the ball after the impact. What is the cause of the change in the kinetic energy of the ball ? Consider the mass of the wall to be infinitely great.

A metallic ball of mass 100 g and specific heat capacity 2 J kg^(-1)K^(-1) was dropped from a height of 6 m on to a perfectly non-conducting surface. If 80% of its kinetic energy is converted into heat on striking the surface, find the change in temperature of the ball. (Take g=1000 cm s^(-2) ).
