A golf ball is hit upward with an initial velocity of 63 meters per second at an angle of 32 with respect to the horizontal The ball is hit from a height of 9 meters above the ground The horizontal distance x from the starting point and the height y above the ground of the ball f seconds after it is hit are given by the parametric equations below x vo cose t y 4 97 v sine t h Here v is the initial velocity is the initial angle with respect to the horizontal and h is the initial height Use the equations to answer the following questions a When does the golf ball reach its maximum height Do not round any intermediate computations Round your answer to the nearest hundredth seconds b What is the maximum height of the golf ball Round your answer to the nearest tenth meters
