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.

An object of mass 1 kg travelling in straight line with a velocity of 10 ms^(-1) collides with it and sticks to a stationary wooden block of mass 5 kg. Then both move off together in the same straight line. Calculate the total momentum before the impact and just after the impact. Also calculate the velocity of combined object.

A bullet of mass 0.04 kg moving with a speed of 90 ms^-1 enters a heavy wooden block and is stopped after a distance of 60 cm. What is the average resistive force exerted by the block on the bullet?

A bullet of mass 20 g is fired horzontally with a of 100 ms^-1 from a pistol of mass 1.5 kg. Calculate the recoil velocity of the pistol.

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.
