1.	A particle is sticked to a disc at a distance r2 m from centre. Disc has initial angular velocity of ωo=6^j rad/s and constant angular acceleration of α=−^j rad/s2 as shown in figure. If radius of disc is 1 m, find the speed of particle after t=2 s.
Answer» A particle is sticked to a disc at a distance $\frac{r}{2} m$ from centre. Disc has initial angular velocity of $ω_{o} = 6^j rad/s$ and constant angular acceleration of $α = -^j {rad/s}^{2}$ as shown in figure. If radius of disc is $1 m$ , find the speed of particle after $t = 2 s$ .
