An object of mass m = 1.00 kg is observed to have an acceleration of a→ with a magnitude of 18.0 m/s2 in a direction θ = 61.5∘ east of north. The figure below shows a view of the object from above. The force F→2 acting on the object has a magnitude of 8.59 N and is directed north. Determine the magnitude and direction of the force F→1 acting on the object. magnitude N direction
