Joey is now on a raft in the ocean, try to sail home. The raft + Joey have a total mass of 195kg. The ocean current produceds a force of 60N eastwaard and the wind produces a force of 95N at 80 degrees. Find the acceleration of the raft (magnitude and direction). If these forces are constant, how long will it take Little Joey to travel 4km?

2. Relevant equations

So I figured out the magnitude of acceleration which is 0.62m/s/s and the direction of acceleration is 50.9 degrees.

3. The attempt at a solution

To find Time

would I use this equation: Distance = (0.5)(a)(t^2)

???

if so, would it be

4000m = (0.5)(0.62m/s/s)(t^2)

and just solve t from there?
