1. For a given height h, use g=9.8 m/s² for the acceleration due to gravity to calculate the
time the ball took in going from the launch position to the floor. Assuming there is no air
resistance, the above y equation becomes
1
0 = h -gt?
2
2. Using this time and the average x, calculate the average initial velocity. Xav = Vayt.
You should present these results along with your data in the table above.
