Solve the problem.A projectile is fired from a height of 7.7 feet with an initial velocity of 153 ft/sec at an angle of 55° with the horizontal. The parametric equations for the path of the projectile are x = (153 cos 55°)t, and y = 7.7 + (153 sin 55°)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.
