A 50000kg ship sails east at 6m/s for 10 minutes. What is the net force acting on the ship? I thought this was so easy but I got it wrong...I had (50000kg*.01m/s^2)...is this because there is no acceleration?

If the ship isn't accelerating then the net force is zero. I would assume it's a constant velocity since it isn't otherwise stated.

Well yeah there is no acceleration so the force would be zerol
F = m*a = 50000 kg (0 m/s^2)
It is moving at a constant velocity for 10 minutes. It doesn't take 10 minutes to reach the velocity. There is a difference.

As the velocity vector is constant( 6m/s and direction east)
the net force is zero as acceleration is 0
and f=m*a(Newton´s 2nd law)
