A mass; m1 = 64 g, sits on a frictionless horizontal surface,
and is attached to a spring of spring constant k = 51 N/m. The
other end of the horizontal spring is attached to a wall; the
system is in equilibrium. Another mass; m2 = 18 g, strikes the
stationary mass m1, and sticks to it. As a result, the spring is
compressed by a distance of 24.5 cm before the masses come to a
momentary stop.
