Answer :
Final answer:
Without the initial speed of the elevator or the distance over which it stopped, we cannot calculate the acceleration of the elevator when it comes to a stop.
Explanation:
The question provided indicates that an elevator, which was moving upward at a constant speed, accelerates to a stop in 0.53 seconds. To find the magnitude of its acceleration during the stopping period, we need additional information such as the initial speed of the elevator before stopping or the distance over which it stops. Since the provided reference texts do not supply this necessary information, we cannot calculate the exact acceleration value. For meaningful physics calculations, specific data is essential.
To calculate acceleration, we would normally use the equation a = rac{ ext{final velocity} - ext{initial velocity}}{ ext{time}}, where the final velocity after stopping is 0 m/s. Without the initial velocity, however, we cannot apply this formula.
