Question

Initially a wheel rotating about a fixed axis at a constant angular deceleration of 0.7 rad/s 2 has an angular velocity of 0 rad/s and an angular position of 8.8 rad. What is the angular position of the wheel after 2.7 s? Answer in units of rad.

Answer 1

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
