a pendulum of length L= 1.25 m. Its bob (which effectively has all the mass) has speed v0 when the cord makes an angle u0 =40.0 with the vertical. (a) What is the speed of the bob when it is in its lowest position if v0 = 8.00 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 u0 is increased by a few degrees?

Question

a pendulum of length L= 1.25 m. Its bob
(which effectively has all the mass) has speed v0 when the cord makes
an angle u0 =40.0 with the vertical. (a) What is the speed of the bob
when it is in its lowest position if v0 = 8.00 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 u0 is increased by a few degrees?
