A 10.5 kg mass is traveling to the right with a speed of 2.10 m/s on a smooth horizontal surface when it collides with and sticks to a second 10.5 kg mass that is initially at rest but is attached to a light spring with force constant 120.0 N/m. (a) Find the frequency, amplitude, and period of the subsequent oscillations. (b) How long does it take the system to return the fırst time to the position it had immediately after the collision?
