1.	A wheel is a rest. Its angular velocity increases uniformly and becomes 80 rad s^(-1) after 5 s. The total angular displacement is
Answer» 800 RAD 400 rad 200 rad 100 rad Solution :`omega=alphat` `:. alpha=(omega)/(t)=(80)/(5)=16 "rad s"^(-2)` `THETA=(1)/(2)alphat^(2)=(1)/(2)(16)(5)^(2)=200` rad
