A lead bullet of mass 21g travelling at a speed of 100 `ms^(-1)` comes to rest in a wooden block. If no heat is taken away by the wood, the rise in temperature of the bullet in the wood nearly is (Sp. Heat of lead 80cal/kg `.^(@)C`)

A lead bullet of mass 21 g travelling at a speed of 100m//s comes to rest in a wooden block . If no heat is taken away by the wood , the rise in temperature of the bullet in the wood nearly is (specified heat of lead = 30 cal//kg^(@)C )

A lead bullet weighing 20 g and moving with a velocity of 100 ms^(-1) comes to rest in a fixed block of wood. Calculate the heat developed and the rise in temperature of the bullet assuming that the half of the heat is absorbed by the bulley. The specific heat of lead is 0.03 cal g^(-1).^(@)C^(-1) .

A bullet of mass 20 g moving with a speed of 500ms^(-1 ) strikes a wooden block of mass 1 kg and gets embedded in it. Find the speed with which block moves along with the bullet.

A bullet of mass 10 g travelling horizontally with a velocity of 150 m s^-1 strikes a stationary wooden block and comes to rest in 0.03 s. Calculate the distance of penetration of the bullet into the block.

A lead bullet of mass 10 g travelling at 300 m//s strikes against a block of wood and comes to rest. Assuming 50% of heat is absorbed by the bullet, the increase in its temperature is (Specific heat of lead = 150 J//kg^(@)C )

A bullet of mass 10 g travelling horizontally with a velocity of 150 m s^-1 strikes a stationary wooden block and comes to rest in 0.03 s. Calculate the force exerted by the wooden block

A bullet of mass 10 kg travelling horizontally with a velocity of 150 ms^(-1) strikes a stationary wooden block and come to rest in 0.03 s. Calculate the distance of penetration of the bullet into the block. Calculate the magnitude of force exerted by the wood in block in the bullet.
