Question #72845

A wheel 2.0 m in diameter lies in the vertical plane and rotates about its central axis

with a constant angular acceleration of 4.0 rad s−2

. The wheel starts at rest at t = 0 and

the radius vector of a point A on the wheel makes an angle of 60º with the horizontal at

this instant. Calculate the angular speed of the wheel, the angular position of the point A

and the total acceleration at t = 2.0s.
