' V 2 m2 m2 Before After Two carts are colliding on an airtrack (neglect friction). The first cart has a mass of m1=45 g and an initial velocity of v1=2 m/s. The second cart has a mass of my=32 g and an initial velocity of V2=-7 m/s. Two experiments are conducted. In the first experiment, the first cart has a final velocity of v1'=-3.28 m/s. What is the velocity of the second cart? 0.425 m/s Computer's answer now shown above. You are correct. Your receipt no. is 163-8286 (? Previous Tries For the second experiment, the bumpers of the carts are modified, but the carts are started with the same initial velocities as before. Now the first cart has a final velocity of v1'=-5.4804 m/s, and the second cart a final velocity of v2'=3.5195 m/s. How much (if any) energy was lost in the collision? -.217 J Submit Answer Incorrect. Tries 2/7 Previous Tries In good approximation, what kind of collision was the second experiment?
