Lecture 7, #2 PROBLEM DESCRIPTION |
Two balls, masses m and 3m, are at rest
a distance d apart. A spring of constant k
and un-compressed length 3d is squeezed between the two balls.
The balls are released
and move apart as the spring un-compresses. Assume that the surface
the balls are on is
frictionless, and neglect air resistance. |
