A simple pendulum of length 1.40 m witha bob of mass 1.10 kg has linearspeed v0 = 3.00 m/s whenthe cord makes an angle q0 = 45.0o with the vertical as shown.
a) What is the speed of the bob which it is at its lowest position?
b) What is smallest value that v0 could have ifthe cord is to achieve a horizontal position during themotion?
c) What is the smallest value that v0 can have sothat the pendulum will not oscillate but rather will continue tomove around in a vertical circle?
