Net force F as a function of time t for a 2.0 kg cart.
A 2.0 kg cart travels along a horizontal, frictionless track in the negative x-direction with a constant speed of 3.0 m/s. Starting at t = 0, a net force in the positive x-direction is exerted on the cart. The magnitude of the force as a function of time is shown in the provided graph.

What is the velocity of the cart at t = 4.0 s?
