Solve the problem.A baseball pitcher throws a baseball with an initial speed of 127 feet per second at an angle of 20° to the horizontal. The ball leaves the pitcher's hand at a height of 4 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 = 119.34t, y = -16t2 + 43.43t + 4
5.238 sec, 1.357 sec,
239.771 feet
B. x = 119.34t, y = -16t2 + 43.43t + 4
2.619 sec, 1.357 sec,
3.997 feet
C. x = 119.34t, y = -16t2 + 43.43t + 4
5.607 sec, 1.357 sec,
29.471 feet
D. x = 119.34t, y = -16t2 + 43.43t + 4
2.804 sec, 1.357 sec,
33.471 feet
