A simple pendulum has a length of L = 0.75 m and a bob with mass of 0.15 kg. The bob is released from an angle of θ = 25◦ relative to a vertical reference line (Fig. 5.34). (a) What is the kinetic energy of the bob when the string is at an angle of 9.0◦? (b) What is the speed of the bob at the bottom of the swing? (Neglect friction and the mass of the string.)
