A 450-g block is attached to a spring of spring constant 45 N/m and is in simple harmonic motion on a frictionless surface with an amplitude of 7.5 cm. A second identical block, moving at 12 m/s in line with the spring, strikes the first one when the spring is at its maximum extension. The two blocks stick together. What is the frequency of the resulting oscillation?

A 450.0 -g block is attached to a spring of spring constant 45 N/m and is in simple harmonic motion on a frictionless surface with an amplitude of 7.5 cm. A second identical block, moving at 1.2 m/s in line with the spring, strikes the first one when the first block is at its equilibrium position and moving away from the second block. The two blocks stick together. What is the amplitude of the resulting oscillation?
