In a lab experiment regarding centripetal forces, students spin a 451g pendulum bob around (see figure). The pendulum bob is supported vertically a by a string, and horizontally by a spring with spring constant, k=104.5N/m. When the radius of the circular path is 17.5cm, the spring is stretched 8.20cm from its equilibrium position. Unfortunately, the students forgot to make certain the string that suspends the pendulum was completely vertical, such that the string made an angle of 8.50o with the vertical
