Asuitcase (mass m = 18 kg) is resting on the floor of an elevator. the part of the suitcase in contact with the floor measures 0.50 m × 0.15 m. the elevator is moving upward with an acceleration of magnitude 1.6 m/s2. what pressure (in excess of atmospheric pressure) is applied to the floor beneath the suitcase?

P=2736 Pa

Explanation:

According to Newton we have that:

∑

A force is exerted by the elevator to the suitcase, according to 3th Newton's law an equal force but in the opposite direction will appeared on the suitcase, that is:

∑

We know that the pressure is given by:
