Problem
A 45kg cooler is pulled across a level sidewalk at constant speed by a rope that makes an angle of 30∘ above the horizontal. The coefficient of kinetic friction between the cooler and the sidewalk is μk=0.20. Determine the magnitude of the tension in the rope required to maintain the constant speed.
