A ball of mass `m` collides with the ground at an angle. With the vertical. If the collision lasts for time `t`, the average force exerted by the ground on the ball is : (e = coefficient of restitution between the ball and the ground)
.

Impulse = change in linear momentum.

`:. Ft = m(eu cos alpha + u cos alpha)` or `F = (m u cos alpha(1 +e))/(t)`.
