## Homework Statement

A constant force of 396 N acts on a spacecraft of mass 7890 kg that has an initial velocity of 34 m/s. How far has the spacecraft traveled when it reaches a velocity of 4890 m/s?

## The Attempt at a Solution

I tried doing F=ma and got the a= 19.92 and then setting up a=(vf-vi)/delta t

Didn't work...

I don't know what I did wrong. Please help. thank you
