A 42-kg girl is standing on a 125-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.17 m/s to the right relative to the plank.

What is her velocity relative to the ice surface?
