A quarterback makes a pass, throwing the ball at 22 m/s and an angle of 62° above the horizontal.
If 19 m is the maximum height of the ball in flight and if it takes 4sec to complete the pass.
How many yards (yd) does he manage to throw the ball? (1 yard = 0.9144 meters)
The receiver has a 22 yard lead from the quarter back by the time he throws the ball. How fast must he run in order to catch the ball when it lands?
