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.
