Can someone explain and show how to arrive at the solution to this multiple choice question please? That is more important to me than simply the right anwser. Thanks!!
Suppose you are standing on the edge of a spinning carousel and step off at right
angles to the edge (radially outward). Now consider it the other way. You are standing
on the ground next to a spinning carousel and you step onto the platform at right angles to
the edge (radially inward).
a) There is no change in rotational speed of the carousel in either situation.
b) There is a change in rotational speed in the first situation but not the
second.
c) There is a change in rotational speed in the second situation but not the
first.
d) There is a change in rotational speed in both instances.
Explanation / Answer
d) There is a change in rotational speed in both instances.-100% sure
you have mass and you are removing mass in the first instance
adding mass in the second the rotational speed should speed up in the first situation and slow down in the second
