1. A cart of mass 4.2 kg is moving at a velocity of 2.7 m/s but then the force shown in the graph below acts on it for 10 seconds. A positive force in the graph represents a force in the same direction as the initial velocity of the cart. a) What is the velocity of the cart at t = 5 s? AF (N) 3 t (s) 10 -2 b) What is the velocity of the cart at t = 10 s?
