Name: You walk into an elevator, step onto a scale, and push the "down" button to go directly from the tenth floor to the first floor. You also recall that your weight is 625 N. Start each of the following parts with a free-body diagram. (a) If the elevator has an initial acceleration of magnitude 2.50 m / s^2, what does the scale read? (b) What does the scale read after the elevator reaches it final speed as it heads to the bottom floor?

Question

You walk into an elevator, step onto a scale, and push the "down" button to go directly from the tenth floor to the first floor. You also recall that your weight is $625 \mathrm{~N}$. Start each of the following parts with a free-body diagram. (a) If the elevator has an initial acceleration of magnitude $2.50 \mathrm{~m} / \mathrm{s}^{2},$ what does the scale read? (b) What does the scale read after the elevator reaches it final speed as it heads to the bottom floor?

Step 1

Identify the forces acting on the person: weight (mg) acting downwards, normal force (N) from the elevator floor acting upwards, and the net force (ma) in the direction of motion (downward). Show more…
