A ball of mass 100 g moving with a velocity of 10ms^-1 is stopped by a boy in 0.25sec. Calculate the force applied by the boy to stop the ball.

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 40 g hits a mud wall with speed 400 m s^-1 . The bullet stops after penetrating 50 cm inside the wall. Find the average resistive force exerted by the wall on the bullets.

A cricket ball of mass 150 g moving with a speed of 126 km/h hits at the iddle of the bat, held firmly at its position by the batsman. The ball moves straight back to the bowler after hitting the bat. Assurming that collision between ball and bat is completely elastic and the two remain in contact for 0.001 s, the force that the batsman had to apply to hold the bat firmly at its place would be
