Question #59993

Answer 1

I would think it would be (A): `1` `"m/s"^2`.

Explanation:

In the image, it appears as if object B is inside of object A, so whatever acceleration object A has should be the exact same as that for object B...

Picture it like this:

If you are running at a constant speed of `4` `"m/s"`, then everything a part of you will also be traveling at `4` `"m/s"`...because where else could your heart, lungs, or brain go except with you?

Answer 2

See below.

Explanation:

Assuming that block B slides inside the cavity frictionless, block B acceleration is composed both of block A horizontal acceleration and this same acceleration downwards. So the resulting acceleration is `norm(1 i -1 j) = sqrt(2)` [m/`"s"^2`]
