(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Within 4 sec of liftoff, a spacecraft that is uniformly accelerating straight upward from rest reaches an altitude of 450 m [up]. What is the spacecraft's acceleration?

2. Relevant equations

The five key equations, plus the velocity, speed, and acceleration equations

3. The attempt at a solution

I don't know what the altitude would be (Displacement? Distance?), so I can't solve the equation with the five key equations.
