Calculating Acceleration of a Ship with Tugboats | Constant Velocity Problem

[PJ81]

Homework Statement

A tanker ship with a mass of 10000Kg is moving with constant velocity into a harbour. Two tugboats interact with the front of the boat with a net force of 10464KN, what acceleration does it undergo?

Homework Equations

a=F/m

The Attempt at a Solution

a=10464000/10000
=1046.4 ms? This sounds pretty wrong to me, I don't even know if this is the right formula to use

welcome to the PF.

F=ma
a=F/m
what you missed i think are both quantities are in kilo versions

Whoops! thanks for that denverdoc.

The Kilogram is the standard unit of measure for mass in the SI system. It looks right to me the only correction I think I have to make is that acceleration is measure in meters per second squared, m/s².

youre right. I think it is a book error or transcriptional error, but figured the result was off by a factor of 1000.
