Solve the problem.A projectile is fired from a height of 6.6 feet with an initial velocity of 113 ft/sec at an angle of 42° with the horizontal. The parametric equations for the path of the projectile are x = (113 cos 42°)t, and y = 6.6 + (113 sin 42°)t - 16t2,where x and y are in feet and t is in seconds. How long does it take the projectile to hit the ground? Round your answer to the nearest tenth of a second.
A. 6.2 sec B. 4.7 sec C. 9.6 sec D. 4.8 sec
