A hammer of mass 500g strikes an iron nail with speed of 50 m/s. If the nail stops , the hammer in a short duration of 0.01s , then find the force acting on the nail by the hammer .

A hammer of mass 400 g, moving at 30 ms^(-1). strickes a nail. The nail stops the hammer in a very short time of 0.01 s. What is the force of the nail on the hammer ? (AS_(1))

In cricket match, a bowler throws a ball of 0.5 kg with a speed of 20 m/s. When a batsman swings the bat the ball strikes with the bat normal to it, and returns in opposite direction with speed of 30 m/s. If the time of contact of the ball with the bat is 0.1s, then the force acting on the bat is......N.

A hammer of mass 1 kg moving with speed of 6 ms^(-1) strikes a wall and comes to rest in 0.1 s . Calculate (i) the impules of force (ii) the retardation of the hammer , and (iii) the retarding that stops the hammer .

A player caught a cricket ball of m ass 150 g moving at a rate of 20 m //s^(- 1) . If the catching process is com pleted in 0.1 s, the force of the blow exerted by the ball on the hand of the player is equal to .....

A particle of mass 50 g is projected horizontally from the top of a tower of height 50 m with a velocity 20m//s . If g=10m//s^(2) , then find the :-

A block of mass 0.50kg is moving with a speed of 2.00m//s on a smooth surface. It strikes another mass of 1 kg at rest and they move as a single body. The energy loss during the collision is

A body of mass 2 kg is rest on a smooth horizontal surface . When a horizontal force of 0.5 N acts on this bofy it is displaced in the direction of the force . Find the work done by the force in 8.0 s .Show that this work is equal to the change in kinetic energy of the body .
