Answer :
Final answer:
The average acceleration of the elevator is calculated using the formula for acceleration which results in an acceleration of approximately 0.73 m/s² upwards.
Explanation:
The question is asking for the average acceleration of an elevator, which can be calculated using the formula for acceleration: a = Δv/Δt , where Δv is the change in velocity and Δt is the change in time. In this case, the change in velocity (Δv) is the final speed minus the initial speed. So, Δv = 2.59 m/s - 0 m/s = 2.59 m/s. The change in time (Δt) is the total time taken, which is 3.55 seconds. Therefore the average acceleration of the elevator is calculated as follows: a = Δv/Δt = 2.59 m/s ÷ 3.55 s = 0.73 m/s². So, the average acceleration of the elevator during this time is approximately 0.73 m/s² upwards.
