3. You step into an elevator on the 44th floor of a tall office building. Each...
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?
Interactive Exercises 5.07: Normal Force and Accelerating Particle For a physics class experiment, you place a Red Delicious apple (mass m = 0.100 kg) at rest on a bathroom scale, and place the combination on the floor of an elevator in a tall building. The elevator is initially at rest-see Interactive Fig. 5.7.1 Cable ty Elevator Apple Bathroom scales Interactive Figure 5.7.1: An apple sits on a bathroom scale that rests on the floor of an elevator. Initially, the elevator...
N3M.12 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. (a) According to chapter N1, an object moving in a circle of radius rat constant speed llexperiences...
