Solve the problem.A projectile is fired from a height of 9.3 feet with an initial velocity of 164 ft/sec at an angle of 41° with the horizontal. The parametric equations for the path of the projectile are x = (164 cos 41°)t, and y = 9.3 + (164 sin 41°)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. 13.6 sec
B. 6.8 sec
C. 6.7 sec
