A body of mass ` 5 kg` is reoving in a circle of diameter ` 0. 30m` making ` 2000` revolutions in (2) minutes, Calculate the linear velocity and centripetal acceleration.

Explanation

Here, ` m = 5 kg, r=0=0 .15 m,
`` (2000)/( 2xx 600 = ( 50)/3 rps `
Leinear velocity, ` v= r omega = r xx 2 piv`
`0.15 zz 2 zz(22)/7) zz (50)/3 = 15.71 m//s`
Centropetal accelration, ` a-c = romega^2 =r pi^2 v^2`
` =(0.15) xx 4 xx (220/70^2 xx 9 50)/3)2 = 1 646.3 ms^(-2)` .
