A player kicks a football at an angle of 35° with the horizontal and with an initial velocity of 14.8 m/s. A second player standing at a distance of 26.0 m from the first player in the direction of the kick starts running to meet the ball at the instant it is kicked.
a. At what rate should the second player accelerate to catch the ball?
b. What would be the speed of the second player upon catching the ball?

Answer:

A.

At 45° the venical and horizontal motions are bulanced The angle that results in maximum range (dx) is 45°, 45 degrees or the angle closest to 45 will result in the greatest horizontal distance traveled. 90 degrees or the highest angle will result in the greatest maximum height reached and the greatest time in the air.

B.

Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.
