    1. The problem statement, all variables and given/known data

    Q: An object thrown upwards at V0 reaches a maximum height of 100 m.
    a. Calculate the initial velocity of V0.
    b. Calculate the total flight time.
    c. Calculate the height of the object when v=30 m/s.

    2. Relevant equations

    That is my question what equations do i need to solve this.

    3. The attempt at a solution

    Sorry i couldn't attempt because i couldn't find the appropriate equation.
