2019 #1 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers a problem from the 2019 AP Physics exam involving two blocks on a frictionless surface, with a focus on graphing the speed of the center of mass. The initial solution incorrectly graphs the speed of block one, leading to a correction. The tutorial also explores angular momentum changes in a sphere pushed by a plunger, emphasizing the role of net torque.

What is the effect of the collision on the momentum of the two-block system?

Explain why the graph of the speed of Block 1 is incorrect according to the problem statement.

What is the relationship between the speed of Block 1 and the center of mass of the two-block system?

Identify the intervals during which the angular momentum of the sphere changes.
