A perfectly inelastic collision, e, = 1 C. A perfectly inelastic collision, e, = 0 D. A perfectly elastic collision, e, = 1 11. Which type of collision is described when two objects move separately after colliding, and both the total momentum and total kinetic energy remain constant? B. nearly elastic C. inelastic D. perfectly inelastic A. elastic 12. What will happen to the colliding bodies in a completely inelastic collision? A. stick together and move as one body after collision and the initial kinetic energy is greater than the final kinetic energy B. bounce away from each other after collision and the initial kinetic energy is equal to the final kinetic energy C. both stopped at the collision point and both momentum and total kinetic energy are conserved D. maintains its initial velocity after colliding and neither momentum nor KE is conserved 13.

The collision is A. elastic C. inelastic 06 mis 14 mis Defore Ater B. characterized by an increased in KE D. not possible because P is not conserved 14. A 1500-kg car is traveling south, and a 2000-kg SUV is traveling west. The total momentum of the system consisting of the two cars is 8000 kg m /s directed 60.00 west of south. The speed of the car in m/s is A. 2.19 B. 2.67 с. 346 D. 4.89 15. A 0.150-kg glider A is moving to the right on a horizontal, frictionless air track with a speed of 0.80 mís. It makes a head-on collision with a 0.300-kg glider B which is moving to the left with a speed of 2.20 m/s. Assume the collision is elastic. What is the magnitude of the final velocity (in m/s) of glider A? A. 0.48 В. 1.48 C. 2.48 D. 3.48
