Question

3. You step into an elevator on the 44th floor of a tall office building. Each floor is 3.50 m above the one below it Youre alone in the elevator. You select your destination floor , then-as you wait for the door to close-you notice: There is a bathroom scale with a mass of 2.43 kg resting on the elevator floor. (Naturally-why wouldnt there be?) You decide to stand on the scales during the ride. (Naturally-why wouldnt you?) Weight (N) Shown here is a time graph of the scales reading of your weight during the ride (For simplicity, treat the ends 808.5 f the graph as infinite-slope discontinuities.) 686 588 t (s) 10 15 20 One other fascinating detail: At time 8.12 s, the single cable that supports the entire elevator had a tension force with a magnitude 16.9 times as much as the normal force exerted by the floor of the elevator on the scale a. What was the greatest tension magnitude in the elevator cable during your ride? b. What was your destination floor?

    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?
