1. The problem statement, all variables and given/known data Material ejected to a height of 2.00 x 10^5m. Acceleration of gravity is 1.80 m/s^2, find initial velocity 2. Relevant equations v (zero) = v - at. 3. The attempt at a solution Seems as though I am missing something since I don't have time or velocity, yet I have distance. Guidance on steps would be appreciated.
