A quarterback throws a football toward a receiver with an initial

speed of 20. m/s at an angle of 30.° above the horizontal.

At that instant the receiver is 20. m from the quarterback. In

(a) what direction and (b) with what constant speed should

the receiver run in order to catch the football at the level at

which it was thrown?

Step 1

a)

The equation for vertical displacement is given by

Step 2

Here θ is the angle, v_{0y} is the vertical component of velocity, a_{y} is the vertical acceleration, t is the time taken.

Step 3

Horizontal distance...
