(Hint: Remember the counter-clockwise rule for positive angular velocity and acceleration.)

(a) Find the angular speed of the wheel at t = 2.30 s.

___ rad/s

(b) Find the linear velocity and tangential acceleration of P at t = 2.30 s.

linear velocity ___ m/s

tangential acceleration __ m/s2

c) Find the position of P (in degrees, with respect to the positive x-axis) at t = 2.30s.

(Hint: Your answer must be between 0 and 360 degrees.)
