Kyle and Jasmine are in an exhibition show. Kyle is on the ground y4,0 = 0 [m], and Jasmine is directly above him at yB,0 = 172.[m]. In their exhibit, Jasmine drops a cannonball at the same time Kyle shoots a similar cannonball directly upward. Kyle's cannonball was launched with enough speed so that both cannonballs will collide just as Kyle's cannonball reached its maximum height. 1. What is the initial speed of Kyle's cannonball? 2. How long after launch did it take for both cannonballs collide? 3. At what height do both cannonballs collide?
