Solve the problem.A projectile is fired with an initial velocity of 300 feet per second at an angle of 45° with the horizontal. In how many seconds will the projectile strike the ground? (Round your answer to the nearest tenth of a second.) The parametric equations for the path of the projectile are x = (300 cos 45°)t, and y = (300 sin 45°)t - 16t2.
