A particle is moving with angular acceleration of `1.2 rad//s^(2)` on a circle of radius 1m. Finds its total acceleration (in `m//s^(2)`) after rotating `sqrt(6)` rad. If its initial angular velocity is zero.

Text Solution

Verified by Experts

The correct Answer is:
5
`omega^(2) =2alpha theta`
`a_(T)=Rsqrt(4alpha^(2) theta^(2) +alpha^(z))=Rasqrt(4theta^(2)+1)`
`=1xx1.2xxsqrt(2.4+1)=6 m//s^(2)`
