To solve this problem, you need to use the free-fall equation: h = gt 2/2. 

set the height of the person (hperson) to 200.0 m. Set vinitial to 50.0 m/s, θ to 0.0 degrees, and g to 9.8 m/s2. 

A. Solve the free-fall equation(h=gt2/2) for t. 
B. Calculate the time it will take the ball to fall to the ground from a height of 200 meters 
and acceleration (g) of 9.81 m/s2. 
C. Based on the time and the horizontal velocity, how far will the ball travel horizontally? 

10. Advanced challenge: Click Reset. Change θ to 30°. Calculate the hang time and distance traveled. (Hint: Use vy = vy(initial) – gt for the time to apex, h = hinitial + gt 2/2 for the height of the apex, and h = gt 2/2 for the time from apex to ground.) 
Predicted hang time: __________ Predicted distance traveled: __________ 
Check your answers: Actual hang time: __________ Actual distance: __________
