Rotaty motion

What is the minimum speed and frequency that we need to rotate with water can in a vertical plane along a circle with a radius of 70 cm to prevent water from spilling?

Correct result:

v =  2.6458 m/s
f =  0.6015 Hz


r=70 cm m=70/100  m=0.7 m g=10 m/s2 Fg=Fo mg=mv2r g=v2r  v=r g=0.7 10=72.6458=2.6458 m/s  ω=v/r=2.6458/0.73.7796 1/rad
ω=2 πf  f=ω2π=3.77962 3.1416=0.6015 Hz

We would be very happy if you find an error in the example, spelling mistakes, or inaccuracies, and please send it to us. We thank you!
