1.A suitcase (mass m = 16 kg) is resting on the floor of an elevator. The part of the suitcase in contact with the floor measures 0.50 m by 0.14 m. The elevator is moving upward, the magnitude of its acceleration being 1.40 m/s2. What pressure (in excess of atmospheric pressure) is applied to the floor beneath the suitcase? 2. P=F/A 3. Force=ma = 16kg*9.1.4m/s/s=22.4 A= .5m*.14m= .07 F/A= 22.4/.07 P= 320 Pa This is wrong, can someone tell me where I went wrong?
