What impulse occurs when an average force of 9 N is exerted on a 2.3 kg cart, initially at rest, for 1.2 s? What change in momentum does the cart undergo? What is the cart's final speed?
Impulse = change in momentum, so change in momentum =
m = 2.3 kg, u = 0, v = ?
The direction of the velocity is in the same direction as the force.
