A flywheel with a diameter of 1 m is initially at rest. Its angular acceleration versus time is graphed in the figure.
(a) What is the angular separation between the initial position of a fixed point on the rim of the flywheel and the point's position 8 s after the wheel starts rotating? (Be sure to give angular separation rather than total angular displacement.)
(b) The point starts its motion at è = 0. Calculate the linear position 8 s after the wheel starts rotating. (Let the initial position of the point be 0.5 .)
Calculate the linear velocity vector 8 s after the wheel starts rotating. (Enter the magnitude.)
Calculate the tangential acceleration vector after the wheel starts rotating. (Enter the magnitude.)
We can't see your figure. There is no point posting such questions here.
