Circular Motion

(Requested by Tricky Bits)

Q- A wheel 1.9 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.15 rad/s2. The wheel starts from rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3o with the horizontal at this time. At t = 2.00 s, find the following.

a) The angular speed to the wheel

b) The tangential speed of the point P

c) The total acceleration of the point P (magnitude and direction)

d) The angular position of the point P
