Solve the problem.A baseball pitcher throws a baseball with an initial speed of 133 feet per second at an angle of 20° to the horizontal. The ball leaves the pitcher's hand at a height of 5 feet. Find parametric equations that describe the motion of the ball as a function of time. How long is the ball in the air? When is the ball at its maximum height? What is the maximum height of the ball?
A. x = 124.98t, y = -16t2 + 45.49t + 5
5.457 sec, 1.422 sec,
263.668 feet
B. x = 124.98t, y = -16t2 + 45.49t + 5
2.729 sec, 1.422 sec,
4.983 feet
C. x = 124.98t, y = -16t2 + 45.49t + 5
5.898 sec, 1.422 sec,
32.333 feet
D. x = 124.98t, y = -16t2 + 45.49t + 5
2.949 sec, 1.422 sec,
