Question

It takes the elevator in a skyscraper 4.0 s to reach:

a) The top floor
b) The ground floor
c) Halfway up
d) The basement

Answer 1

The time taken by an elevator in a skyscraper to reach different floors depends on the height and acceleration of the elevator. It takes 4.0 seconds for the elevator to reach the ground floor from rest.

Step-by-step explanation:

The time taken by an elevator in a skyscraper to reach different floors depends on the height and acceleration of the elevator. Let's examine each option:

1. The top floor: We don't have enough information to determine the time taken to reach the top floor. The height and acceleration of the elevator are needed.
2. The ground floor: The elevator starts from rest, so it takes 4.0 seconds to reach the ground floor.
3. Halfway up: Again, we don't have enough information to make an accurate calculation.
4. The basement: We don't have any information about the basement.
