You step into a high-speed elevator on the top floor of a tall building and push the button for the first floor. The elevator accelerates downwards. How does the normal force N exerted on you by the floor of the elevator compare to your weight? Select one: O a. the normal force is equal to your weight O b. It depends on how fast you are moving O c. the normal force is greater than your weight O d. the...

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?
iii. How must the reading on the scale compare with the reading
you make when the elevator...

You walk into an elevator, step onto a scale, and push the "up" button. You recall that your normal weight is 621 N . When the elevator has an upward acceleration of magnitude 2.70 m/s2 , what does the scale read? (792 N) If you hold a 3.81-kg package by a light vertical string, what will be the tension in this string when the elevator accelerates as in the previous part?

Problem 1: A 1000.0 kg elevator is controlled with a cable. Friction and air resistance can be ignored. In this problem, the elevator is already moving downward at a constant speed of 1.0 m/s. During this initial stage, the elevator moves with this constant speed for 1.5 seconds. Then, in a 2nd stage, the elevator slows down to a stop with constant acceleration. During this 2nd stage, it takes 0.5 seconds of time to come to a stop. A. Draw...

between figure the acceleration arrow you should draw through each position dot during step 1 should point from the puck's position at that instant toward the table's center, since the Ca string's tension force acts in that direction.] (b) Check your work using the Newton program. N3M.12 In this problem, we will explore the necessary con- t ditions for uniform circular motion.
