Abox has a weight of 150N and if being pulled across ahorizontal floor by a force that has a magnitude of 110N. The pulling force can point horizontally, or it can point above the horizontal at an angle θ. When the pulling force points horizontally, the kinetic frictional force acting on the box is twice as large as when the pulling force points at the angleθ. Find θ.
