Final answer:
The time it takes for an elevator to stop depends on factors such as initial velocity, acceleration or deceleration, and distance. For example, if an elevator starts from rest and decelerates at a rate of 2 m/s², it would take approximately 5 seconds to stop.
Step-by-step explanation:
The time it takes for an elevator to stop depends on various factors such as the initial velocity of the elevator, the acceleration or deceleration it undergoes, and the distance it needs to cover before stopping. Let's consider an example to understand this better:
If an elevator starts from rest and decelerates at a rate of 2 m/s², it would take approximately 5 seconds for the elevator to come to a stop. However, the actual time may vary based on different scenarios and conditions.
