SUMMARY
A mass of 3.5 kg is suspended from a string of length 1.47 m and revolves in a horizontal circle with a tangential speed of 3.44 m/s. The angle theta between the string and the vertical is calculated using the centripetal force formula Fc = mv²/r. The resulting angle is approximately 35 degrees from the vertical. This calculation is essential for understanding the dynamics of circular motion in physics.
