a) A 0.339 kilogram pendulum bob passes through the lowest part of its path at a speed of 2.70 m/s. Determine the tension in the pendulum cable at this point if the pendulum is 72.0 centimeter long?
b) When the pendulum reaches its highest point, find what angle does the cable make with the vertical?
c) Determine the tension in the pendulum cable when the pendulum reaches its highest point?
