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:

prolly a beacuse the momentuem the car has increases while going down hill

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
