Substitute the given value of 
into 
. Calculate the value of 
. Create the ordered pair )
using the given value of and the calculated value of .
Note: at the moment the rock is released is equal to zero.
Note: The second part of your question asks about the velocity after 
. The calculation of using will give you the velocity at the exact instant . All you know about any time after that is that the velocity will be greater than that calculated. Personally, I would write the answer as )
and challenge the teacher/instructor/professor/whatever to prove me wrong.
