An NFL punter at the 15-yard line kicks a football with an initial velocity of 95 feet per second at an angle of elevation of 28 degrees. Let (t) be the elapsed time since the football is kicked.
a. Write the parametric equations of this problem.
b. With (t)=0 at the time of the kick, how many seconds is the ball in the air?
c. Where does the ball land given the kick is straight and from the 15 yard line?
