How much time does it take to complete one revolution ?

1018 · Answer

half a minute?

1018 · Answer

30 s

ganeshie8 · Answer

which is same as 30 seconds

ganeshie8 · Answer

$\omega = \dfrac{2\pi}{T} = \dfrac{2\pi}{30}$ rad/sec

ganeshie8 · Answer

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

hey can you help i cant seem to get the answer. :(

1018 · Answer

having a hard time with the rev/min

christos · Answer

Well you are gonna have to convert rev/min into rev/sec

christos · Answer

before you do anything else

christos · Answer

then you have to convert use that to find T (period)

christos · Answer

T = 1 revolution
