Packages having a mass of 6 kg slide down a smooth chute and land horizontally with a speed of 3 m/s on the surface of a conveyor belt. If the coefficient of kinetic friction between the belt and a package is μk = 0.2, determine the time needed to bring the package to rest on the belt if the belt is moving in the same direction as the package with a speed v = l m/s.
