Momentum, Impulse and Recoil
... • Ft = ∆(mv) • The momentum, mv, is the amount gained before the cord begins to stretch. Ft is the impulse the cord supplies to reduce the momentum to zero. • Because the rubber cord stretches for a long time, a large time interval t ensures that a small average force F acts on the jumper. • The cor ...
