A 0.350 kg birdie is being hit between two badminton players. The graphs show the birdie's velocity and the force exerted on the birdie by the badminton racket. If the birdie is in contact with the racket for Δt=5.40 ms, what is the maximum force exerted on the birdie?

Answer 1

force*time=massbirdie(change in velocity)
you can solve for force. Remember change in velocity is vf-vi, and at impact, the birdie travels in opposite direction (v has a change of sign)
