Two identical billiard balls striks a rigid wall with the same speed but at different angles , and get reflected without any change in speed , as shown in Fig . What is (i) the direction of the force on the wall due to each ball ? (ii) the ratio of the magnitudes of impulses imparted to the balls by the wall ?

As shown in fig. two identical balls strike a rigid wall with equal speeds but a different angles of incidence. They are reflected back without any lose in speed. (a) Determine the direction of force exerted by each ball on the wall. (b) Determine the ratio of impulse imparted by the two balls on the wall in both cases.

A ball of mass m strikes a rigid wall with speed v and gets reflected without any loss of speed, as shown in the figure. (a) What is the magnitude of the impulse imparted to the ball by the wall? (b) What is the direction of the force on the wall due to the ball?

A particle of mass m strikes a wall with speed v at an angle 30^(@) with the wall elastically as shown in the figure. The magnitude of impulse imparted to the ball by the wall is

Two billiard balls of equal mass 30 g strike a rigid wall with same speed of 108 kmph (as shown) but at different angles. If the balls get reflected with the same speed then the ratio of the magnitude of impulses imparted to ball 'a' and ball 'b' by the wall along 'X' direction is

A riding ball of mass m strikes a rigid wall at 60^(@) and gets reflected without loss of speed as shown in the figure below. The value of impulse imparted by the wall on the ball will be.

A ball of mass m strikes a rigid walJ with speed u and rebounds with the same speed. The impulse imparted to the ball by the wall is

A ball of mass m strikes a rigid walJ with speed u and rebounds with the same speed. The impulse imparted to the ball by the wall is

A batsman hits back a ball straight in the direction of the bowler without changing its initial speed of 15m/s.If the mass of ball is 0.1kg then impulse imparted to the ball will be
