Finding half of initial value?

I am instructed in a question to find half of the initial velocity if the max. height of a ball going upward is 37 m. I believe I have found the initial velocity to be 26.9 m/s - so I'm thinking the rest should be simple, right?

For instance if I took the kinematics equation v = v_0 + at, I should be able to rearrange and solve for half of v_0, correct? Or something...?

Thanks!

Huh?
If v_o = 26.9 [m/s] , half of v_o = 13.45 [m/s] .

Did you want to find the *time* when v = 1/2 v_o ,
or the elevation where the object has 1/2 v_o ?
Did you want to find the velocity at half the 37 [m] ,
or the elevation at half the rise time?

Sorry... I'm looking for the height (elevation) when the object has 1/2 its initial velocity... does that clarify?
