Chapter 9, Problem 21(choose chapter or problem)
The figure shows the parametric equations and the path for a ball thrown from a height of 5 ft, with an initial speed of 100 ft /s and at an angle of 45 with the horizontal. (So except for the initial angle, the data are the same as in Exercise 20.) (a) Compute the x- and y-coordinates of the ball when t 1, 2, and 3 seconds. (Round the answers to one decimal place.) (b) How long is the ball in flight? (Round the answer to two decimal places.) What is the total horizontal distance traveled by the ball before it lands? (Round to the nearest foot.)
