# A \( 60.0 \)-\( \text{cm} \) diameter wheel rotates with a constant angular acceleration of \( 4.00 \) \( \text{rad/s}^2 \). It starts from rest at \( t = 0 \), and a chalk line drawn to a point, \( P \), on the rim of the wheel makes an angle of \( 57.3^\circ \) with the horizontal at this time. At \( t = 2.00 \) \( \text{s} \), find (a) the angular speed of the wheel, (b) the linear velocity and tangential acceleration of \( P \), and (c) the position of \( P \).

A \( 60.0 \)-\( \text{cm} \) diameter wheel rotates with a constant angular acceleration of \( 4.00 \) \( \text{rad/s}^2 \). It starts from rest at \( t = 0 \), and a chalk line drawn to a point, \( P \), on the rim of the wheel makes an angle of \( 57.3^\circ \) with the horizontal at this time. At \( t = 2.00 \) \( \text{s} \):

**Part a)** Find the angular speed of the wheel. *(3 points)*

**Part b)** Find the linear velocity and tangential acceleration of \( P \). *(3 points)*

**Part c)** Find the angular position of \( P \). In other words how many degrees did \( P \) rotate through. *(3 points)*
