Answer #1

according to newton's first law

when a body continues in a state of rest or a state of uniform motion contimues in the same state until net external force acted on it.

here 60 kg girl is on the smooth and frictionless frozen surface so there is no net horizontal force acted on her. therefore she does not change her position .
