4. Consider the two carts shown below. What do you suppose happens to the total mechanical energy during an elastic collision? spring bumper 5. Dynamics cart A has a mass of 1.8 kg and is moving with a velocity of 4.0 m/s[right] along a frictionless track. Dynamics cart 2 has a mass of 2.2 kg and is moving at 6.0 m/s[left]. The carts collide in a head-on elastic collision cushioned by a spring (k = 8.0 x 10¹ N/m). cart 1 cart 2 a. Determine the compression of the spring, in centimetres, during the collision when cart 2 is moving at 4.0 m/s[left]. (Hint: find the velocity of the cart 1 first and then use conservation of energy to find the amount of compression.) b. Calculate the maximum compression of the spring, in centimetres. (Hint: at maximum compression both gliders will have the same velocity - if they did not they would be catching up to or pulling away from each other.)
