A space shuttle is launched from the earth. It reaches an altitude of 100 meters in 6.1 seconds. At 6.1 seconds, a ball is dropped and hits the ground in 8.5 seconds. What is the speed of the space shuttle when the ball is dropped? I am really stumped by this one d=0.5at^2 100=(0.5)a (6.1s)^2 a=5.37m/s^2 Vf=vi+at v=(5.37m/s^2) * 6.1s v=32.757m/s?
