Homework Statement
A football is thrown toward a receiver with an initial speed of 20.0 m/s at an angle of 30.0o above the horizontal. At that instant, the receiver is 20.0 m from the quaterback. In what direction and with what constant speed should the receiver run in order to catch the football at the level at which it was thrown? Why is the x-component velocity of the football's path not the speed at which the receiver should run?
Homework Equations
The Attempt at a Solution
I understand how to do this problem, but I don't understand why the speed at which the receiver should run to catch the football at the level it is thrown is not equal to the x-component of the football; wouldn't both velocities have to be equal for the receiver to make the catch?
