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...
