Question
The figure shows a pendulum of length L = 1.7 m. Its bob (which effectively has all the mass) has speed vo when the cord makes an angle
Oo = 32° with the vertical. (a) What is the speed of the bob when it is in its lowest position if vo = 8.8 m/s? What is the least value that vo
can have if the pendulum is to swing down and then up (b) to a horizontal position, and (c) to a vertical position with the cord remaining
straight? (d) Do the answers to (b) and (c) increase, decrease, or remain the same if 6o is increased by a few degrees?
