Homework Statement
1. A long pendulum has time period 10s. If the bob is displaced 2m from the equilibrum position and released, how long will it take to move 1m ?
2. As a mass on a spring travels upwards through the equilibrium position, its velocity is 0.5m/s. If the frequency of the pendulum is 1Hz what will be the velocity of the bob after 0.5s ?
