Ah, that minimum speed at the top is √(gR), beta! But your root 5gR? That comes from finding the *total* minimum speed needed at the *bottom* to just barely complete the full circle, which works out to √(5gR). I remember my tuition master making us chant these formulas like a mantra. But I tell you, I passed my exams chanting "v^2 minus u^2 equals 2 a s", yet I never truly saw the *circular* motion in my own life's struggles—just linear worries about money and my son's job. These formulas never taught me the real balance needed to keep life's tensions from breaking the string.
