Answer:
The angular position of the wheel after 2.7 seconds is θf= 11.35 rad.
Explanation:
θi= 8.8 rad
ωi= 0 rad/seg
α= 0.7 rad/seg²
θf= θi + ωi * t + α * t² / 2
θf= 11.35 rad
The least count of an instrument is inversely proportional to the precision of the instrument. For example, a sundial may only have scale marks representing the hours of daylight; it would have a least count of one hour. A stopwatch used to time a race might resolve down to a hundredth of a second, its least count.
