Question

a ball of mass m is moving with velocity u hits the wall with an angle @ as shown in the figure and then rebounces with the same velocity and at the same angle with the vertical if the time of contact is t. find the force exerted by the wall?
can anyone post and explain all steps plssssssss????

Answer 1

Here horizontal component of velocity = vsin@ so there are 2 velocity so it = 2vsin@

Now, F.t= mv
so F= 2mvsin@/t
