Part 2: 1. (a) The vertical position of the ball increases at an increasing rate until it reaches the peak, after which the vertical position decreases at an increasing rate. (b) Yes, the vertical velocity changes throughout the toss because it goes from positive velocity to negative velocity, resulting in zero velocity. The peak is where the ball changes direction. (c) The vertical acceleration is negative because the slope is decreasing (because it becomes less positive) and velocity is decreasing. (d) The ball is released from the thrower’s hands @ __ and the time just before the ball is caught is @ ___ because the ball isn’t released and/or caught at t=0. At these points, the slope is the steepest at these points. (e) Yes, the ball was released at this point because it was the point where the rate of displacement over time (velocity) was the highest/steepest. (f) The horizontal position of the ball increases at constant rate. (g) No, the horizontal velocity does not change; it’s constant.
