Newton's 2nd Law: Determine Force Magnitude (6.05 N, 6.1 m/s, 2.5 kg)

[liamtcarroll]

A 2.5 kg mass accelerates at 6.1 m/s
in adirection 37◦north of east. One of the two
forces acting on the mass has a magnitude of
6.05 N and is directed north.
Determine the magnitude of the second
force.
Answer in units of N
I know you have to break it up into multiple components, but otherwise i don't have a clue of what to do

If a mass accelerates in a certain direction, the net force applied to the mass must act in the same direction.

F = ma is a vector equation.

ya, key word here is net force, two forces accelerating at 6.1m/s/s, one of which was given, just get the N and magnitude correct for the other.

if you are the marker for my exam, i think i'll be gone! amended the units for acceleration...hahaha

Just pointing out the acceleration is 6.1 m/s². It was beginning to bug me now that I've seen it in multiple threads :-)
