Students perform an experiment using two low-friction laboratory carts. A piece of timer tape is attached to Cart I and fed through a spark timer apparatus. The timer makes a mark on the tape each 0.10 s. Cart I is pushed toward Cart [I which is initially at rest. The carts collide, the piece of clay is deformed and holds the carts together as they continue to move. The mass of Cart I is 2.20 kg.

Speed of Carts I and II (After the Collision) as a Function of the Speed of Cart I (Before the Collision) N Speed of carts I and 11 after the collision (cm/s) 0 1 2 3 4 5 6 7 Speed of Cart I before the collision (cm/s) The collision of the two carts is classified as i because if . Select one: O a. i = elastic, /i = momentum is conserved O b. i = elastic, /i = kinetic energy is conserved O c. i = inelastic, /i = momentum is not conserved O d. i = inelastic, /i = kinetic energy is not conservedBased on a point on the line of best t, if Cart I had a speed of 4.0 cm/s before the collision,then the combined speed of the two carts after the collision would be (Lb cm/s. You will need to record the values of a and b. Based on the slope of the line of best t,the combined mass of the two carts is e.f kg. You will need to record the values of e and f. The values of a, b, e,and f are (do not include commas, letters, spaces or decimals)
