A body of mass `2 kg ` revolves in a circle of diameter ` 40 cm`, making 12 0` revolutions per minute. Calculate its linera velcity and centripetal avveleration.

Explanation

Here , ` 2 r=05 m, omega =2.3 ms^(-2)`
`alpha =6 rad s^(-2)`
Tangential acceleration,
`a_(T) =t_(alpha)=0.5 xx 6 =3.0 ms^(-2)`
Centripetal acceleration,
Magnitude of total linear acceleration,
`a =sqrt (a_(T)^(2) + a_(C)^(2)) =sqrt((3.0)^(2) + (3.125)^(2))`
`4.33 ms^(-2)`.
