A ball is moving horizontally and strikes a vertical wall from which it rebounds horizontally. The sketch graph shows how the contact force F between ball and wall varies with time of contact t.

The maximum value of F is F₀ and the total time of contact between ball and wall is T.

What is the change in momentum of the ball?

A. $\frac{{{F_0}T}}{2}$

B. ${F_0}T$

C. $\frac{{{F_0}}}{{2T}}$

D. $\frac{{{F_0}}}{T}$
