SUMMARY
The discussion focuses on calculating the tension in a string during uniform circular motion, specifically for a rock swung in a horizontal circle with a radius of 0.95 m and a period of 0.75 s. The user successfully calculates the tangential velocity (V) as 7.9587 m/s using the formula V=(2*pi*r)/t. However, they encounter difficulty in determining the tension (Ft) without knowing the mass (m) of the rock, despite recognizing that mass cancels out in the centripetal force equation (Fc=(mv^2)/r).
