Solve the problem.A projectile is fired from a height of 9.7 feet with an initial velocity of 124 ft/sec at an angle of 54° with the horizontal. The parametric equations for the path of the projectile are x = (124 cos 54°)t, and y = 9.7 + (124 sin 54°)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. 12.7 seconds B. 6.3 seconds C. 6.4 seconds D. 8.1 seconds
