Solve the problem.A baseball player hit a baseball with an initial velocity of 170 feet per second at an angle of 40° to the horizontal. The ball was hit at a height of 3 feet off the ground. 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 horizontal distance the ball traveled?
