....

anonymous · Answer

At what angle?

anonymous · Answer

Seems like info is missing...height, angle, equation?

anonymous · Answer

There isn't enough information given to answer this question. You need to know the vertical component of the velocity, and assume that by "hitting the ground" they mean to return to the initial height. With an angle for the velocity, you can decompose it into it's horizontal and vertical components. You can then apply the basic kinematic equations to find when the ball returns to it's initial height (presumably of zero).

anonymous · Answer

that is all the question asks.

anonymous · Answer

Well, we can assume that the 192 feet per second is purely vertical, I suppose...

The acceleration of gravity is -32.174 ft/s^2. Do you know the kinematic equation to use to solve this?
