A 0.444 kilogram pendulum bob passes through the lowest part of its path at a speed of 2.12 meter per second. Obtain the tension in the pendulum cable at this point if the pendulum is 71.6 centimeter long?
When the pendulum reaches its highest point, obtain what angle does the cable make with the vertical?
Find what is the tension in the pendulum cable when the pendulum reaches its highest point?
