A major league baseball pitcher throws a pitch that follows these parametric equations: x(t) = 146t y(t)=-16t² + 6 + 5. The time units are seconds and the distance units are feet.

(a) Calculate the horizontal velocity of the baseball at time t; this is the function x'(t)= | 146 (b) What is the horizontal velocity of the baseball when it passes over homeplate? 146 (c) What is the vertical velocity of the baseball at time t; this is the function y'(t)=-32t+6 (d) Recall that the speed of the baseball at time t is s(t)=√ [x '(t)]² + [y' (t)]² ft/sec. What is the speed of the baseball (in mph) when it passes over homeplate? (e) At what time does the baseball hit the ground, assuming the batter and catcher miss the ball? (f) What is the magnitude of the angle at which the baseball hits the ground? mph. ft/sec. ft/sec ft/sec. sec. rad. (This is the absolute value of the angle between the tangential line to the path of the ball and the ground. Give your answer in radians to three decimal places.)
