A ball moving with a momentum of 5kg ms^(-1) strikes against a wall at an angle of 45^(@) and is reflected at the same angle Calculate the impulse .

A ball moving with a momentum of 5 kg ms^(-1) strikes against a wall at an angle of 45^@ and is reflected at the same angle. Calculate the change in momentum.

A 0.5 kg ball moving with a speed of 12 m//s strikes a hard wall at an angle of 30^(@) with the wall. It is reflected with the same speed and at the same angle . If the ball is in contact with the wall for 0.25 s , the average force acting on the wall is

A 0.5 kg ball moving with a speed of 12 m/s strikes a hard wall at an angle of 30^(@) with the wall. It is reflected with the same speed and at the same angle. If the ball is in contact with the wall for 0.25 s, the average force acting on the wall is :

A 1 kg ball moving with a speed of 20 m/s strikes a hard wall at an angle of 30^(@) with the wall. It is reflected with the same speed at the same angle. If the ball is in contact with the wall for 0.5 seconds, the average force acting on the wall is

A ball moving with a momemtum 5 kg "ms"^(-1) strikes a wall. If the initial and final momenta make equal angles of 45^(@) , then magnitude in change in momentum is

A ball of mass 50 g moving at a speed of 2.0 m/s strikes a placne surface at an angle of incidence 45^0 . The ball is reflected by the plane at equal angle of reflection with the same speed. Calculate a. the magnitude of the change in momentum of the ball b. the change in the magnitude of the mometum of the ball.

A ball of mass 0.5 kg moving with a velocity of 2 ms^(-1) strikes a wall normally and bounces back with the same speed. If the time of contact between the ball and the wall is one millisecond, the average force exerted by the wall on the ball is
