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.
