An NFL punter at the 15 -yard line kicks a football with initial velocity of 90 feet per second at an angle of elevation of $70^{\circ}$ Let t be the elapsed time since the football is kicked.
(a) Write parametric equations that represent the distance the football travels. Assume that x=0 represents the 15 -yard line.
(b) What interval represents the possible values for t ?
(c) What is the distance the ball travels in feet downfield (to the nearest whole number)?
