A ball of mass m bounces back b/w two surfaces with a speed u .
a) find the average force on each wall.
b) If one surface slowly move toward the other with a speed of v <<<< u .find the force exerted by the ball on moving surface .the gravity is neglected & the collision is perfectly elastic.

a. if 2l is smaller than u....then no of collisions per sec= u / 2l so av force on each wall= change in momentum per second av force= (2mu)* u/2l
