18M.1.HL.TZ2.7

A ball of mass m collides with a vertical wall with an initial horizontal speed u and rebounds with a horizontal speed v. The graph shows the variation of the speed of the ball with time.

M18/4/PHYSI/HPM/ENG/TZ2/07

What is the magnitude of the mean net force on the ball during the collision?

A. $\frac{{m(u - v)}}{{({t_2} + {t_1})}}$

B. $\frac{{m(u - v)}}{{({t_2} - {t_1})}}$

C. $\frac{{m(u + v)}}{{({t_2} + {t_1})}}$

D. $\frac{{m(u + v)}}{{({t_2} - {t_1})}}$
