Block 1 is attached to a spring and oscillates on a horizontal frictionless tabletop. When block 1 is at a point of maximum displacement, block 2 is brought from above and placed directly on top of block 1 without interrupting the oscillation. The two blocks stick together. How do the period of oscillation and the maximum kinetic energy with both blocks compare to those of block 1 alone? (Hint: assume no work is done on the system when the second block is introduced.)
