merry
go
round

8
If you just step off, the
merry
go
round
will keep going the same speed (angular speed).
9
In this case, the system would be the bullet plus the
merry
go
round
and there is an external force.
10
It is ok, the net torque on the
merry
go
round
is zero (which really should be a vector).
11
This would be costly and time consuming organisational

go

12
In this week's episode, the MythBusters were seeing if they could make a

13
