The pendulum having a mass of 0.100kg was released. The string made a 7.0 degree angle with the vertical. The bob of the pendulum returns to the lowest point every 0.10 s.
i) Determine the period? Find out its frequency?
ii) The pendulum is substituted by one with a mass of 0.300 kg and set to swing with a 15 degree angle. Do the given quantities increase, decrease or remain similar?
• period
• frequency
• total energy
• speed at the lowest point
