Created by StemPy LabA block hangs at rest from a light vertical spring and stretches it by . The block is pushed up by and released from rest. Take . What is the period of the motion, and how does the largest force of the spring on the block compare with the smallest?

← A block of mass 0.40 kg lies on a smooth table between two walls. A spring of force constant 30 N/m joins it to the left wall and a spring of force constant 50 N/m joins it to the right wall. Later the two springs are joined end to end, and the block is attached to one end of this pair on the same smooth table, the far end fixed to one wall. How does the period in the second set-up compare with the period in the first?Two blocks, of mass 1.5 kg and 3.5 kg, lie on a smooth horizontal table, joined by a light spring of force constant 420 N/m. They are pulled apart until the spring is 5.0 cm longer than its natural length, held still, and then both are let go at the same moment. What is the greatest speed of the 1.5 kg block in the motion that follows? →
