Answer

a, b. Cannonball A. c. It depends on which angle is closer to 45 degrees.

Work Step by Step

a. Cannonball A is launched at the larger angle. It has a larger initial vertical velocity. According to Eq. 2–11c, it will have the larger vertical displacement. b. According to equation 2.11a, it will also take more time before that large velocity component is reduced to zero. c. According to the level horizontal range equation, page 63, a cannonball with a launch angle closest to 45 degrees travels farthest.
