Homework Statement
A particle of mass 2kg is moving under the action of two forces. They
are of magnitudes 12N and 8N, acting at an angle of 60
to each other. Find
the magnitude of the acceleration of the particle and its direction relative to the
direction of the 12N force.
Homework Equations
F = ma.
The Attempt at a Solution
I know that this isn't actually a tricky problem but I can't seem to think it out properly.
Am I correct in decomposing both the 12N and 8N forces into vector form, i.e. 12cos60i = 12sin60j and 8cos60i + 8sin60j respectively. Then summing them and calculating both the magnitude and direction using tanθ = vj/vx. Is this correct? I'm sort of confused by the whole "relative to the 12N force" part. Thanks.
