A 0.69 kg mass is observed to accelerate at 8.16 m/s2 in a direction 30.5° 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?

forceNorth= mass*accelerationNorth

forceEast= mass*acceleartionEast

so break up the acceleration in to N, and E components.
