But what is angular momentum? Let's take a step back. Linear momentum is the product of an object's mass and its velocity (direction and speed). A passenger in a moving car that stops abruptly ...

Step 1: FBDs Draw an FBD of A+P. Step 2: Kinetics (linear impulse/momentum) Look for forces acting in the x-direction for your FBD. Is linear momentum conserved in that direction? Also, note that you ...
