PHYS 121 Lecture Notes - Lecture 10: Compact Car, Headon, Hockey Puck
Document Summary
All diagrams taken from "l10_energy. pdf" on the course canvas website. Quiz: a compact car and a large truck collide head-on and stick together as they slide on an icy road. Which undergoes the larger magnitude of momentum change: car, truck, the magnitude of the momentum change is the same for both vehicles, cannot tell without knowing the final velocity of combined inertia. A: the system is isolated so momentum is conserves in the collision. Momentum can be transferred from one object to another, but it cannot be created or destroyed. In this case momentum is transferred from the truck to the car. Quiz: two balls of equal mass are thrown horizontally with the same initial velocity. They hit identical stationary boxes resting on a frictionless horizontal surface. The ball hitting box 1 bounces back, while the ball hitting box 2 gets stuck.
