Homework Statement
A body is thrown into the air with an initial velocity of v0. What initial velocity is required to double the maximum height previously attained?
Homework Equations
The Attempt at a Solution
I found the max height v02/64 at v0 by solving for 't' in the velocity equation when 'v' = 0, and subbing that for 't' in the height equation and solving. I then multiplied this by 2 and set it to the height and tried to solve for v0 and ended up with v02 = -512t2 + 32tv0. I then solved for v0 and ended up with v0 = 16t. Do I need to somehow find 't' or did i stray off course somewhere and end up with the wrong answer?
