Question #1 - #7: Motion on an incline and in a collision
Students were experimenting with objects in a collision. Ball A moves
with a constant acceleration by sliding down a frictionless incline plane
before colliding with Ball B. Students used motion detectors to
measure the velocity of Ball A at various points.
