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 = 45.0^o 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?
