A ball of mass m is moving with a

velocity u rebounds from a wall with

same speed . The collision is assumed

to be elastic and the force of interaction

between the ball and the wall varies as

shown in the figure given below . The

value of F_{m} is

Δ P = 2 m u

Δ P = \int_{0}^{2 T} F (t) d t = F_{m} T

F_{m} T = 2 m u

F_{m} = \frac{2 m u}{T}
