Solve the problem.A projectile is fired from a height of 6.5 feet with an initial velocity of 123 ft/sec at an angle of 52° with the horizontal. The parametric equations for the path of the projectile are x = (123 cos 52°)t, and y = 6.5 + (123 sin 52°)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. 146.8 ft B. 300.1 ft C. 153.3 ft D. 159.8 ft
