Your cat bats at one of its toys so that the toy slides straight across the living room floor. The toy leaves the paw of the cat with a velocity of vo = 2.3 m/s. The toy slides 2.4 meters across the floor before coming to rest. Assume there is a constant force of friction on the toy as it slides, which slows it down (ignore air resistance). What is the magnitude of the force of friction on the 0.31 kg toy?
