Solve the problem.A baseball pitcher throws a baseball with an initial velocity of 128 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 = 120.28t; y = -16t2 + 43.78t + 4;
2.825 sec;
