Impulse and Momentum example 1

The video tutorial explains how to determine the velocity of a 20 kg cart being pulled by a time-varying force. It begins with setting up the problem and drawing a free body diagram. The impulse-momentum formula is introduced and applied in the X direction. The integral of the force over time is split into two parts to simplify the calculation. The video concludes with solving the integral to find the cart's velocity after 4 seconds, which is 30 meters per second to the right.
