Suppose the simple pendulum shown below were released from an angle of θ = 74°, with L = 0.73 m and m = 0.25 kg..What angle of release would give half the speed of that for the 74° release angle at the bottom of the swing?
You know what? No one is going to give you an answer. Jot down the formulas. You can do that much right?
