Case a: a "happy ball" collides with the floor moving at 2 m/s and rebounds upward at 1 m/s.
case b: a "sad ball" with the same mass collides the floor moving at 2 m/s and stops.
the collision time is the same for each case.
which variable is different for these two cases?
which case involves the greatest momentum change? the greatest impulse? the greatest force?
