1. The problem statement, all variables and given/known data
This is more of a math question - I just want to know how I can find the value of t when v=0.

0=5(t3/2)-(27/2)(t^1/2)+9(t^-1/2)

2. Relevant equations

3. The attempt at a solution

I do not know how to solve this. Please show steps. Thanks.
