A 50gram lead bullet, specific heat 0.02 is initially at 30^(@) C. It is fired vertically upwards with a speed of 840 m// s . On returning to the starting level, it strikes a cake of ice at 0^(@)C .

A block of a mass of 10 kg rests on a horizontal table. The coefficient of friction between the block and the table is 0.05. When hit by a bullet of mass 50 g moving with speed v, that gets embedded in it, the block moves and comes to rest after moving a distance of 2 m on the table. If a freely falling object were to acquire speed 10v​ after being dropped from height H, then neglecting energy losses and taking g=10 S.I. , the value of H is close to:
