SUMMARY
The discussion centers on calculating the amplitude of a mass-spring system following a collision. A 120g mass rolls down a frictionless hill, achieving a speed of 4.2 m/s before colliding with a 3.00g mass attached to a spring with a constant of 30 N/m. The final velocity after the collision is determined to be 1.2 m/s, and the angular frequency (w) is calculated as 8.45 rad/s. The correct amplitude (A) is confirmed to be 0.266 m, leading to the motion equation x(t) = 0.266sin(8.44t).
