A rubber ball of mass `0 *4` kg hits the ground at same angle without any change in speed . If the speed of ball is 1 m/s and the period of contact between the ball and floor is `0*4` s, find the average force exerted by the ball on the ground .

A ball of mass 0.5 kg moving with a velocity of 2 m//s strikes a wall normally and bounces back with the same speed . If the time of contact between the ball and the wall is 1 millisecond , the average force exerted by the wall on the ball is

A golf player hits a golf ball of mass 100 g and imparts it a speed of 50 m/s. If golf stick remains in contact with the ball for 0.01 s, then the average force exerted by the golf stick on the ball.

A golf player hits a golf ball of mass 100 g and imparts it a speed of 50 m/s. If golf stick remains in contact with the ball for 0.01 s, then the average force exerted by the golf stick on the ball.

A 3-kg steel ball strikes a wall with a speed of 10.0ms^(-1) at an angle of 60.0^(@) with the surfaces of the wall. The ball bounces off with the same speed and same angle. If the ball was in contact with the wall for 0.2s, find the average force exerted by the wall on the ball.
