Question

A small ball is thrown with initial speed u at angle thetha with horizontal. The ball makes several impacts before surface . Coefficient of resitution is e. Find time of flight

Answer 1

Initial velocity in x direction = ucosthetha

in y direction = usinthetha

Let Vy be the final y direction velocity after collision.

Therfore,

E = Vy/Uy => Vy/(usinthetha)

Vy = E*usin(thetha).
