Solution: A 25-kg picnic cooler falls off the bed of a flatbed truck on the entrance ramp of the PG5 garage and proceeds to slide down the ramp at a constant speed. Architectural drawings of the garage show that the ramp is inclined at an angle of θ. Draw the appropriate freebody diagram and then find an algebraic expression for the coefficient of kinetic friction. Simplify the result as much as possible.
