A 47.7 kg person is standing on a 77 kg plank. The plank is originally at rest on a frozen, frictionless lake. The person begins to walk along the plank at a constant velocity of 2.06 m/s to the right relative to the plank.
What is the plank's velocity relative to the ice surface in m/s?
I realize this is a momentum problem, I just don't know how to solve for the velocity of the plank with respect to the ice or of the person with respect to the ice or what a "right relative to the plank" is...
Any help is appreciated as always
