A 8.70-kg box is sliding across the horizontal floor of anelevator. The coefficient of kinetic friction between the box andthe floor is 0.460. Determine the kinetic frictional force thatacts on the box for each of the following cases.
(a) The elevator is stationary.
(b) The elevator is accelerating upward with an acceleration whosemagnitude is 2.70 m/s2.
(c) The elevator is accelerating downward with an accelerationwhose magnitude is 2.70 m/s2.
