A stone of mass 5 kg. tied to one end of a rope of length 0.8 m, is whirled in a vertical circle. Find the minimum velocity at the highest point and at the midway point.
[g = 9.8 m/s2]
m = 5 kg, r = 0.8 m, g = 9.8 m/s2
Minimum velocity at the highest point (vH) = ?
Minimum velocity at midway point (vM) = ?
At highest point,
The minimum velocity at the highest point is 2.8 m/s. At midway point,
