A quarterback is set up to throw the football to a receiver who is running with a constant velocity, directly away from the quarterback and is now a distance Daway from the quarterback. The quarterback figures that the ball must be thrown at an angle @ to the horizontal and he estimates that the receiver must catch the ball a time interval f, after it is thrown to avoid having opposition players prevent the receiver from making the catch. In the following you may assume that the ball is thrown and caught at the same height above the level playing field. Assume that the y coordinate of the ball at the instant it is thrown or caught is y=0 and that the horizontal position of the quarterback is 2-0. (Figure 1) Use g for the magnitude of the acceleration due to gravity, and use the pictured inertial coordinate system when solving the problem.
