You drag a trunk of mass m across a level floor using a massless rope that makes an angle with the horizontal. Given a kinetic-friction coefficient (μ), Find the minimum force needed to move the trunk with constant speed. Do not answer in terms of theta; essentially, if you were allowed to vary the angle at which you pull the trunk, what is the minimum force required?
