... constant of 2.0 × 106 N/m. What is the maximum compression of the spring? (Neglect the mass of the spring.) 15. The kinetic friction force between a 60.0-kg object and a horizontal surface is 50.0 N. If the initial speed of the object is 25.0 m/s, what distance will it slide before coming to a stop? ...

... Force of gravity acts on the object as though all the mass were located at the CM of the object. (Proof coming up!) If we pivot the object somewhere else, it will orient itself so that the CM is directly below the pivot. This fact can be used to find the CM of odd-shaped objects. ...
