By the way,  it is not enough to say that the ball's initial velocity is  20  feet per second.

Since velocity is a vector,  the direction of the initial velocity must be specified,  too.


Also,  should I think that the crater is like a deep well ?         (ha-ha-ha . . . )

Then the problem should say it . . .
