Question
In Activity 3-1, the center of mass of the pendulum bob is a distance h1= 118.0 cm above the floor when the bob is at the equilibrium position. The pendulum bob is pulled back and released from a point where the bob?s center of mass is at a height of h2 = 166.0 cm above the floor. In the lab you will measure the bob ?s speed as It swings through the bottom of its arc using the velocity vs. time graph produced by the motion sensor. a) What will be the speed of the pendulum bob as it reaches the bottom of the swing. Use g = 9.8 m/s^2) m/s b) If the length L of the pendulum is 71.8 cm, what is the angle theta when the bob is released?Explanation / Answer
In Activity 3-1, the center of mass of the pendulum bob is a distance h1= 118.0
