A 41.0-cm diameter disk rotates with a constant angular acceleration of 3.00 rad/s$^2$. It starts from rest at $t = 0$, and a line drawn from the center of the disk to a point $P$ on the rim of the disk makes an angle of
57.3$^\circ$ with the positive $x$-axis at this time.
(a) At $t = 2.48$ s, find the angular speed of the wheel.
____ rad/s
(b) At $t = 2.48$ s, find the magnitude of the linear velocity and tangential acceleration of $P$.
linear velocity ____ m/s
tangential acceleration ____ m/s$^2$
(c) At $t = 2.48$ s, find the position of $P$ (in degrees, with respect to the positive $x$-axis).
____ $^\circ$ counterclockwise from the $+x$-axis
