Question

1. a bucket of water of mass 5 kg is tied with a rope of length 50cm is rotated in a vertical circle.if the bucket rotates 10 rotations i 1 min,calculate the maximum velocity with which it can be rotated without spilling the water at the highest point

Answer 1

m g  = m v² / r

v = √(r g)  = √ (0.50 9.8)  = 2.21 m / s
