1. (50 POINTS) On a frictionless air track, a 0.5000 kg-glider moving to the right at 2.950 m/s collides with a 0.4000 kg glider moving to the left at 1.950 m/s. The collision is elastic. Assume the right direction is the positive direction of motion. (HINTS WILL BE PROVIDED NEXT WEEK: Use the number of significant digits indicated in this text. The numbers used in the graphs have one less sig. fig. but are useful to see as numbers that compare with each other in terms of masses and speeds. THE LEFT BLOCK HAS LARGE MASS AND SPEED. THE RIGHT BLOCK HAS SMALLER MASS AND SPEED THAN THE LEFT BLOCK. Untitled21.png (a) (15 points) What is the velocity of the 0.5000 kg-glider after the collision? (b) (15 Points) What is the velocity of the 0.4000 kg-glider after the collision? (c) (8 points) Using the velocities of parts (a) and (b), compute the total kinetic energy of the system after the collision. Do not round off during intermediate computations. (d) (8 points) Using the initial velocities before the collision, compute the total kinetic energy of the system before the collision. Do not round off during intermediate computations. (e) (4 points) Are the answer to parts (c) and (d) equal? Explain.
