HW S IK O.O Part 1 of 2 OP A projectile is launched from the ground with initial velocity 88 ft per sec. The parametric equations x = 50.5t and y = - 16t + 72.1t model the pat (a) Determine the angle 0 that the projectile makes with the horizontal at launch. (b) Write parametric equations for the path using the cosine and sine functions. . . . (a) The angle that the projectile makes with the horizontal at launch is 0 ~ (Round to the nearest tenth as needed. Do not include the degree symbol in your answer.)
