Physics 209A Fall 2023 Name Sonoma State University Pre-Lab: Collisions For Problems 1 and 2, define and explain the terms. Use a mix of equations and words. 1. Momentum 2. Conservation of momentum 3. What is the difference between elastic and inelastic collisions in degards to Conservation of Total Energy vs Conservation of Mechanical Energy. Does each type of collision conserve the two quantities? 4. A system is composed of two masses. They move along a line, one mass moving faster than the other. Eventually, they collide, stick, and move off as one object. Given Show your calculations and final results Object masses: a. Initial momentum of each mass mi and mz. m1=2.0 kg i. P1 = m2=5.0 kg ii. P2= Initial velocities: V11 = 2.0m/s V21 = 1.5m/s b. Total initial momentum of the system? p1 + p2 5. After the above collision, what is the final velocity? (Show calculations and final results)
