Conservation of Momentum using Unit Vectors

The video tutorial explores the physics of a Nerd-A-Pult system, focusing on the conservation of momentum. Initially, the problem is set up with a ball launched from a stationary Nerd-A-Pult. The tutorial explains how internal forces in the x-y plane conserve momentum, leading to the calculation of the Nerd-A-Pult's final velocity. The solution involves substituting mass and velocity into the momentum equation. The tutorial concludes with a discussion on the results, emphasizing the consistency of physics principles.

What did Billy conclude about the physics of the situation?

Why do the ratios of the y and x velocities of the ball and the Nerd-A-Pult equal the same number?

Describe the significance of the angles in the context of the final velocities of the ball and the Nerd-A-Pult.
