merry-go-round as seen from above
is shown in Fig. 11-47a with a conve-
nient coordinate system. A bit after
the merry-go-round has started and
is going around uniformly, we start

If it is, write "Yes" and give a reason why you think so. If it isn't,
write “No" and specify the type of force and the object responsible
for exerting it.
