A 2 kg pendulum bob is hanging from a 30 cm long piece of string. If the pendulum bob is allowed to move in circular motion in a horizontal plane, determine the tension in the string if the angle the string makes with the vertical is 37 degrees.

mg is the downward force, mv^2/r is the centripetal force, tension is the string force at the angle. Tan theta= tension/mg solve for tension.
