A suitcase (mass m=16kg) is resting on the floor of an elevator. The part of the suitcase in contact with the floor measures 0.50m by 0.15m. The elevator is moving upward, the magnitude of its acceleration being 1.5m/s^2. What pressure (in excess of atmospheric pressure) is applied to the floor beneath the suitcase? This problem isn't too hard. Elevator is going up so the pressure will be greater than normal produced by the suitcase. Take the area of the suitcase and continue from there?
