In this virtual laboratory you will investigate projectile motion with and without air resistance. You will find the maximum range of a football with given initial velocity and the launch angles required for it to hit a target.
Procedure:
Open the Projectile Motion interactive animation.
 
(a) Given the initial speed there are two launch
angles for the football to hit the center of the target.  
(b) Given an initial speed there are two launch angles
for the football to hit the center of the target.  
(c) Given the initial speed, find the maximum range of the projectile
along the horizontal ruler.
Measure this distance with the ruler, do not
use the number displayed by the simulation. The simulation displays
the distance traveled by the ball before it hits the ground.  
(d) Now set initial speed of the
projectile at 20 m/s. Find the maximum range of the
projectile along the horizontal ruler. For this maximum range note the launch angle and the hang
time of the football and estimate the maximum height of the football
above the ground during its flight.

Projectile speed: 20 m/s
