 Q1. A mass M hangs in equilibrium on a spring. M is made to oscillate about the equilibrium position by pulling it down 10 cm and releasing it. The time for M to travel back to the equilibrium position for the first time is 0.50 s. Which line, A to D, is correct for these oscillations?
It is pulled down 10 cm therefore the maximum displacement from the equilibrium (amplitude) is 10 cm. To travel from the displacement to the equilibrium position is a quarter of the whole cycle (A to midpoint to-A to midpoint to A (again)). Therefore period is 2.0 s |
