Two carts with frictionless wheels are moving on a level surface. Cart 1, the red cart, has a mass im, . 1 kg and a velocity of 10 cm/s. Cart 2, the green cart, has a mass mi, = 2 kg and is moving at , =-15 cm/s. After the collision they move apart. 1 -10 omy/'s -15 cmy's Before collision After collision 3. What type of collision Is it? A. This Is an elastic collision. B. This Is an Inelastic collision. This Is a perfectly (or totally) Inelastic collision. D. This Is an explosive (or superelastic) collision. E. Not enough Information Is given to answer It. Additional questions to test your understanding (Conservation of momentum) 4. In a perfectly inelastic collision (choose all that apply): A. Linear momentum Is conserved. B. Kinetic energy Is conserved C. The objects stick together after the collision. D. The objects don't stick together after the collision. 5. In an inelastic collision (choose all that apply]: A. Linear momentum Is conserved. B. Kinetic energy Is conserved. C. The objects stick together after the collision. D. The objects don't stick together after the collision. 6. In an elastic collision (choose all that apply): A. Linear momentum Is conserved. B. Kinetic energy Is conserved. C. The objects stick together after the collision. D. The objects don't stick together after the collision. 7. One railroad car is travelling to the right at speed v. It collides Into an Identical railroad car which Is at rest, and after the collision, they lock together. What Is their common speed after the collision? A. V B. C.8. In the previous question, was kinetic energy conserved during the collision? Hint: You can easily figure out the Initial and final kinetic energies. Do NOT use your Intuition! A. Yes B. NO C. Cannot determine without the numerical values of m and v. 3. A person of mass 175 Ibs. runs and Jumps Into a stationary cart of mass 300 Ibs. The Initial speed of the person Is a my's. What Is the final speed of the cart after the person Jumps In? Express your answer In my's and Input the number only. 10. What Is the change In kinetic energy from before to after the collision of the system (person + cart)? Express your answer In J and Input the number only. If It's negative, Input the minus sign. Hint: Don't forget to convert
