A girl of mass Mg is standing on a plank of mass Mp. Both are originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity Vgp to the right relative to the plank. (The subscript "gp" denotes the girl relative to the plank.)
Required:
a. What is the velocity vpi of the plank relative to the surface of the ice?
b. What is the girl's velocity vgi relative to the ice surface?
