Question

I am only stuck on part C. I have tried two answers that I got and they aren't correct.

A baseball player throws a baseball when it is 5 ft above the ground. The ball leaves his hand at an angle of 16° with respect to the ground at velocity 156 ft per sec. (a) Determine the parametric equations that model the path of the projectile. (b) Determine the rectangular equation that models the path of the projectile. (c) Determine approximately how long the projectile is in flight and the horizontal distance covered. O A x= (16 cos 156°)t, y= - 16t2 + (16 sin 156°)t +5 OB. X = (5 cos 16°), y = - 16t? + (5 sin 16°)t + 156 C. x= 156 cos (16°)t, y= - 16t2 + 156 sin (16°)t +5 OD. x=(16 cos 5°)t, y= - 1612 + (16 sin 5°)t + 156 (b) Choose the correct rectangular equation below. OA. y=5 156 sin 2160 1562ano+(cos 16°)x [ OB. y=5– 16x² + 156x y=5-54 cos 216° 1521 cos 2160 +(tan 16°) seconds. (c) The ball is in the air for approximately (Round to two decimal places as needed.)
