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?

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?
4. After collision, both cannonballs got stuck together and moved
directly downward with an initial speed of u0= 1/2 √ (gyB,0). How
long after collision will it take for both balls to reach the ground?
