To find the final speed of the elevator, we need to first calculate the acceleration that the elevator undergoes and then use that acceleration to find the final speed.
Given:
Initial velocity (u) = 0 (Starting from rest)
Acceleration (a) = 3.125 m/s^2
Time (t) = 4.0 seconds
We can use the formula of motion to find the final velocity (v):
v = u + at
Plugging in the values:
v = 0 + 3.125 * 4.0
v = 12.5 m/s
Therefore, the final speed of the elevators is 12.5 m/s.
The elevators in the landmark Tower and Yokohama Japan, are among the fastest in the world they accelerate upward at 3.125 (m/s^2) for 4.0 seconds to reach their final velocity. If these elevators start from rest, what is their final speed
