31. 

The boy throws a snowball such that it strikes the wall of the building at the maximum height of its trajectory. If it takes t = 1.5 s to travel from A to B, determine the velocity vA at which it was thrown, the angle of release , and the height h.

[A]. vA = 12.00 ft/s, = 24.4E, h = 21.7 ft
[B]. vA = 49.8 ft/s, = 76.0E, h = 39.7 ft
[C]. vA = 36.3 ft/s, = 24.4E, h = 18.2 ft
[D]. vA = 48.3 ft/s, = 65.6E, h = 39.7 ft
