A giant spaceship exlporing where no one has gone before travels at a constant acceleration of m/s². When the spaceship passes planet Physicsto its speed is m/s. How fast was the spaceship going 30 seconds earlier?

I go outside and climb up on the roof of the building. I pull a rock and a stopwatch out of my pocket. Being careful not to hit Martin below, I drop the rock and time how long it takes for the rock to hit the ground. The stop watch says seconds. How tall is the building?
