A spring with spring constant k is attached to mass M. The spring is horizontal and mass M sits on a horizontal frictionless table. On the side of mass M opposite to the spring a cord is attached that runs over a pulley (which you may take to be ideal: zero mass, zero moment of inertia, and frictionless). The cord is attached to a hanging mass m.
Find the equilibrium position of the masses. (That means: How far does the spring stretch from its un-stretched length?)

A 45.4 kg girl is standing on a 144 kg plank. The plank, at first 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 1.60 m/s relative to the plank. Wha..
