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.

What is the mass of the cart being pulled?

How does the force P of T change over time according to the graph?

Describe the forces acting on the cart as depicted in the free body diagram.

What is the impulse and momentum formula mentioned in the text?

What is the initial velocity of the cart?

Explain how to calculate the area under the graph for P of T.

What is the final velocity of the cart after 4 seconds?
