A 2.03 kg mass is observed to accelerate at 8.82 m/s2 in a direction 28.8° north of east. There is a force directed north acting on the object and a force directed east acting on the object. What is the magnitude of the force acting east on the object?
Use F=ma to get the resultant force.
Fcos(θ)=force acting due east, and
Fsin(θ)=force acting due north.
