The figure shows a pendulum of length L = 2.6 m. Its bob (which effectively has all the mass) has speed v0 when the cord makes an angle θ0 = 42° with the vertical. (a) What is the speed of the bob when it is in its lowest position if v0 = 9.1 m/s? What is the least value that v0 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 θ0 is increased by a few degrees?

The figure shows a conical pendulum, in which the bob (the small
object at the lower end of the cord) moves in a horizontal circle
at constant speed. (The cord sweeps out a cone as the bob rotates.)
The bob has a mass of 0.024 kg, the string has length L = 1.2 m and
negligible mass, and the bob follows a circular path of
circumference 1.2 m. What are (a) the tension in the string and (b)
the period...

A simple pendulum of length 0.50 m has a 0.30-kg bob. At t = 0,
the bob passes through the lowest position in its motion, and at
this instant it has a horizontal speed of 0.39 m/s . A. What is the
maximum angular displacement ϑmax away from vertical that the
pendulum reaches? B. What is the magnitude of the bob's linear
speed v when it has angular displacement ϑmax/2?
