1. How do the average measured and calculated velocities for the ball right after the collision compare? (Values are about the same if the percent difference is less than 10%.)
a. measured < calculated
b. measured > calculated
c. measured is about the same as calculated
2. How do the average measured and calculated distances traveled by the block compare? (Values are about the same if the percent difference is less than 10%.)
a. measured < calculated
b. measured > calculated
c. measured is about the same as calculated
3. Based on the average measured velocity for the ball right after the collision, is it likely that the collision between the ball and the block is totally elastic?
a. No, some kinetic energy was lost in the collision.
b. No, some kinetic energy was gained in the collision.
c. Yes, the total kinetic energy was conserved in the collision.
