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

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.
