## Homework Statement

a wheel 2m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4rad/s^2. The wheel starts at t=0 and the radius vector of a certain point P on the rim makes an angle of 57.3° with the horizontal at this time. At t=2s find d.) the angular position for point P.

## Homework Equations

The answer for d.) is 9radians but can someone help me figure out how to get this. Also if you could help show me how to get the direction of the total acceleration.

## The Attempt at a Solution

I already found that angular speed, ω=8rad/s, tangential speed v=8m/s, and total acceleration is 64.12m/s^2
