Oh, I had wrong understanding of involvement of energies in harmonic motion, apparently... Thanks for you help Doc Al.

So mechanical energy will stay the same after the collision? I thought it will change because it depends on angular frequency which in turn depends on mass.

Spring with k=100N/m attached to the ceiling. Someone attaches mass of 1kg to the spring. After the spring reaches equilibrium another mass of 50g is dropped from a height of 2m above the 1st mass. After the collision of m1 and m2 the masses merge and continue to move. a) Find extension of...
