The velocity of A is 5.16m/s²
<u>Explanation:</u>
Given-
mass of cylinder A, mₐ = 2kg
mass of cylinder B, mb = 10kg
Distance, s = 2m
Velocity of A, v = ?
Let acceleration due to gravity, g = 10m/s²
We know,

We know,


Therefore, the velocity of A is 5.16m/s²
Explanation:
may I ask what it is on because I might be able to help out
Answer:
Well, it has to do something with the force of the train. It's pulling you, a force of gravity
However jumping off results in a different sort of energy, the train know is moving farther away as you jump down. So you end up in a different place
