Dynamics question: You are riding in an elevator that is going up at 10ft/s. You are holding your cell phone 5ft above the floor when it suddenly slips out of your hand and falls to the floor. Will it hit the elevator floor in more time, equal time, or less time than it would take if the elevator were standing still? Show work justifying your answer.

E. Suppose you are standing on the scale in the elevator and the
elevator is accelerating downward with
an acceleration smaller than 9.8 m/s2
i. Draw free-body diagrams of yourself, the scale, and the floor
of the elevator where it interacts
with the scale.
ii. How must the magnitude of the force exerted by the scale on
you compare with your own
weight?
