ok, but still I don't understand whether the weight force affects the value of the impact force.
The ball is being dropped vertically, so do we add the weight force to dp/dt?
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.
I know:
F = m[delta]v
...[delta]t
and
F = mg , where g= -9.8 N/kg
But what is the...
