To find out forward force of a ship

[paddygills]

Homework Statement

the mass of a ship is 15000kg. force of friction is 12000n acceleration is 2m/s2. find resultant force and thn the forward force

Homework Equations

resultant force = mxacc
15000x2=30000

The Attempt at a Solution

unable to calculate the forward force but think it must involve the 12000n

You will have the forward force acting one way and the frictional force acting in the opposite direction. The sum of these two forces (taking direction into account) will give you the resultant force (which you calculated already).
