Solve.A baseball pitcher throws a baseball with an initial speed of 140 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 = 131.56t and y = -16t2 + 47.88t + 5 3.094 sec, 1.496 sec, 40.82 feet B. x = 124.04t and y = -16t2 + 45.14t + 5 5.856 sec, 1.411 sec, 31.838 feet C. x = 124.04t and y = -16t2 + 45.14t + 5 5.412 sec, 1.411 sec, 259.702 feet D. x = 124.04t and y = -16t2 + 45.14t + 5 2.706 sec, 1.411 sec, 4.99 feet
