On a horizontal, frictionless table, an open-topped 5.50kg box is attached to an ideal horizontal spring having force constant 390N/m. Inside the box is a 3.44-kg stone. The system is oscillating with an amplitude of 7.50cm . When the box has reached its maximum speed, the stone is suddenly plucked vertically out of the box without touching the box.
Find the period of the resulting motion of the box. Answer in seconds.
Find the amplitude of the resulting motion of the box. Answer in meters.
