A 1.3 kg mass accelerates at 5.8 m/s2 in a
direction 36◦ north of east. One of the two
forces acting on the mass has a magnitude of
17.3 N and is directed north.
Determine the magnitude of the second
force.
Answer in units of N.

F=ma
so figure net force from ma
then
netforce=17.3N+F
solve for F.
TO make the net force more manageable, change the acceleration to N, E components first.
