Question

2. Allison throws a tennis ball graphical analysis (Allotted Time 45 minutes) Allison throws a tennis ball at timet0 from a height above the ground equal to her own height. We assume that the positive horizontal direction is the positive r-direction, and the positive vertical direction is the positive y-direction. The ball has At times and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that each bounce is instantaneous. We also assume that each time the ball bounces, its horizontal speed just after the bounce is the same as its horizontal speed just before the bounce, but its bertical speed just after the bounce is 3/4 its vertical speed just before the bounce a positive initial horizontal velocity v,, and no initial vertical velocity. 2.1. Let x, y, , y, a, a, be the x and ycomponents of the ball's position, velocity, and acceleration respectively. Sketch graphs of the following quantities between time 0 and time 1-匆You may ignore what the graph looks like at the times and when drawing your graphs. y versusx xversus yversus s versus , versus a versus y versus Your sketches do not need to contain labels indicating values on the axes they should, however, have the e features, like the shape of the and relative size of various s of the
