Solve the problem.A projectile is fired from a height of 8.4 feet with an initial velocity of 174 ft/sec at an angle of 53° with the horizontal. The parametric equations for the path of the projectile are x = (174 cos 53°)t, and y = 8.4 + (174 sin 53°)t - 16t2,where x and y are in feet and t is in seconds. Determine the maximum height reached by the projectile. Round your answer to the nearest tenth of a foot.
A. 310.1 ft B. 318.5 ft C. 611.9 ft D. 301.7 ft
