5. A football is kicked off with an initial speed of 64 ft/s at a projection angle of 45 °. A receiver 180 ft. away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to catch the ball just before it hits the ground? Neglect air resistance. Answer: 5.61 m/s um elevation 1
