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. In the figure, determine the character of the collision. The masses of th the velocities before and after are being given. The collision is A elastic C. inelastic blocks and betere 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 is directed 60.00 west of south. The speed of the car in mis is A 2.19 B. 2.67 C. 3.46 D. 4.89
