When dropping a metal ball onto a foam mat what is the formula for the impact speed. I know the impact speed, rebound speed, the mass of the ball and time of the ball on the mat.(adsbygoogle = window.adsbygoogle || []).push({});

I know:

F = m[delta]v

.......[delta]t

and

F = mg , where g= -9.8 N/kg

But what is theimpact force?

Is it F = m[delta]v + mg ?

.............[delta]t
