which is same as 30 seconds

  • ganeshie8
\(\omega = \dfrac{2\pi}{T} = \dfrac{2\pi}{30}\) rad/sec

next use the formula centripetal acceleration = \(\omega^2r\)

having a hard time with the rev/min
Christos
  • Christos
Well you are gonna have to convert rev/min into rev/sec
Christos
  • Christos
before you do anything else
Christos
  • Christos
then you have to convert use that to find T (period)
Christos
  • Christos
T = 1 revolution
