Determine the acceleration of an elevator in a high-rise building if it increases its speed by 3.2 m / s for 2 seconds.

These tasks: ΔV (increase in the speed of the elevator in a high-rise building) = 3.2 m / s; t (duration of the acceleration of the lift) = 2 s.

To determine the acceleration of the considered elevator in a high-rise building, we will use the formula: a = ΔV / t.

Let’s calculate: a = 3.2 / 2 = 1.6 m / s2.

Answer: The elevator in question in a high-rise building moved with an acceleration of 1.6 m / s2.
