A simple pendulum is made from a string that is 0.65m in length with a mass of 0.2kg attached to the free end. The mass is pulled to one side during a small angle and released from rest.
1) What is the angular frequency and period of the pendulum? If the mass were doubled, to 0.4kg, what would be the new angular frequency and period?
2) How long would it take for the mass to reach its greatest speed? Why?
3) If this pendulum were placed on the moon, would its period be greater or less than on the earth? Why?
A box of mass 0.500 kg hangs from a vertical spring with k =30.0 N/m. The box is at rest at the spring’s equilibrium positionwhen a lump of putty with mass 0.100 kg falls on the box from above and sticksto it. Just before striking the box the putt..
