A football is thrown toward a receiver with an initial speed of 16.2 m/s at an angle of 35.6 degree above the horizontal. At that instant, the receiver is 14.0 meter from the quarterback. The acceleration of gravity is 9.81 m/s2. Find with what constant speed should the receiver run to catch the football at the level at which it was thrown?
Answer in units of m/s.
