james pushed his 10 kg cart with a constant horizontal force of 9.0 Newtons over a distance of 3.1 meters. If all frictional forces are neglected and the cart started from rest, what is the grocery cart's final speed in meters per second?

Work done = kinetic energy increase

9.0 * 3.1 = (1/2)*M*V^2 = (0.5)*10*V^2

Solve for V
