A 47.1 kilogram girl is standing on a 162 kilogram 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 1.49 meter per second relative to the ice surface in the direction of the positive x-axis.

Determine the velocity of the plank relative to ice surface?

Find the velocity of the girl relative to the plank?
