Question
A quarter back passes a football at a velocity of 50 ft/s at an angle of 40 degrees toward an intended receiver 30 yd downfield. The pass is released 5 ft above the ground. Assume that the receiver is stationary and that he will catch the ball if it comes to him. Will the ass be completed? If not, will the throw be long or short?
xt- Demonstrates the horizontal change, the distance the ball covers in order to reach the receiver 30 yd downfield. Gravity doesn't affect the football so the ball has a constant velocity resulting in a straight line
Vx- Demonstrates the constant velocity the ball had throughout the time it flew to the receiver. The velocity of the ball doesn't change, which makes the graph look like a line.
yt- Shows the vertical change of the ball. The graph is an upside down parabola because this shows how the ball goes up and then down due to gravity
Vy- Demonstrates how the quarterback threw the football at a certain velocity. How it slowed down at its peak point and then came back down with more velocity heading towards the ground. The negative sloped line is caused by the ball decelerating toward the earth.
