The drag on a pitched baseball can be surprisingly large. Suppose a 145 g baseball with a diameter of 7.4 cm has an initial speed of 40.2 m/s (90 mph). Drag coefficient for a pitched baseball equals 0.35.

Part A: What is the magnitude of the ball's acceleration due to the drag force?

Part B: If the ball had this same acceleration during its entire 18.4 m trajectory, what would its final speed be?
