Question 181

Multiple Choice

Find a rectangular equation for the plane curve defined by the parametric equations.
-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?
