Determine the kinetic frictional force that acts on the box for each of the following cases. (a) The elevator is stationary. N (b) The elevator is accelerating upward with an acceleration whose magnitude is 1.20 m/s2. N (c) The elevator is accelerating downward with an acceleration whose magnitude is 1.20 m/s2.
If a 63.4 kg person stood on the floor in an elevator accelerating upward with 0.41g, what would be the magnitude of the force exerted on the floor by the person? (b) What would be the magnitude of the force if the elevator were accelerating downward with 0.54g?
A 62-kg woman in an elevator is accelerating downward at a rate of 1.6 m/s2. What is the magnitude of the force exerted by the elevator floor on the woman's feet?

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...
A 2 kg block is sitting on a 4 kg block in an elevator. The elevator is accelerating downward at 2 m/s^2. A) What is the force of the floor on the bottom box? B) What is the force of the top box on the bottom box?
