The graph shows the motion of a lift starting at rest and initially moving upwards: What is the acceleration of the lift between 0 and A?

0.67 m/s²

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s

Final velocity (v) = 2 m/s

Time (t) = 3 secs

Acceleration (a) =?

Acceleration can be defined as the rate of change of velocity with time. It can be represented mathematically as:

Acceleration = change in velocity /time.

a = (v – u) /t

With the above formula, we can calculate the acceleration of the lift as shown below:

Initial velocity (u) = 0 m/s

Final velocity (v) = 2 m/s

Time (t) = 3 secs

Acceleration (a) =?

a = (v – u) /t

a = (2 – 0) /3

a = 2/3

a = 0.67 m/s²

Thus, the acceleration of the lift between 0 and A is 0.67 m/s².

this is a good question! i'll do some research and come back when i have the answer!
