Question: Problem 4 . The 4 - kg cart, at rest at time t = 0 , is acted on by a horizontal force which varies

Problem 4.
The 4-kg cart, at rest at time t=0, is acted on by a horizontal force which varies with time t as shown. Neglect friction and determine the velocity of the cart at t=1s and at t=3s.
Hint: The equation of the parabola is x2=4ay.
