Two masses, m1 and m2 are joined by a massless spring and lie on a frictionless horizontal surface. The spring has constant k and unstitched length. Required:
Find the characteristic frequencies and normal coordinates when the system is put in motion.

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.

The amount of potential energy possessed by an elevated object is equal to
