A ball of mass 400 g travels horizontally

along the ground and collides with a

wall . The velocity - time graph below

represents the motion of the ball for the

first 1.2 seconds .

The magnitude of average force between

the ball and the wall is

F_{a v g} = \frac{m △ v}{△ t} = \frac{(0.4 k g) (10 m / s)}{(0.2 s)}

= 20 N .
