The document contains 15 multiple choice questions about projectile motion. It covers topics like the path of a projectile, direction of acceleration, time to hit the ground from different heights, use of trigonometry to find horizontal velocity, effect of initial vertical velocity on time to highest point, and questions about maximum/minimum velocity and acceleration at different points in a projectile's path.
