Answer 1

Calculation of the Acceleration of the Elevator

To find the acceleration of the elevator, we can use the kinematic equation:

h = h0 + v0t + (1/2)at^2

where: - h is the final height (2 m) - h0 is the initial height (0 m) - v0 is the initial velocity (0 m/s) - t is the time (1 s) - a is the acceleration of the elevator (to be determined)

Plugging in the given values, we can solve for the acceleration:

2 = 0 + 0 * 1 + (1/2) * a * 1^2

Simplifying the equation:

2 = (1/2) * a

Multiplying both sides by 2:

4 = a

Therefore, the acceleration of the elevator is 4 m/s^2.
