A 40.0-cm diameter disk rotates with a constant angularacceleration of 3.00 rad/s2. It starts from rest at t = 0, and aline drawn from the center of the disk to a point P on the rim ofthe disk makes an angle of 57.3° with the positive x-axis at thistime.
(a) At t = 2.45 s, find the angular speed of the wheel.
(b) At t = 2.45 s, find the magnitude of the linear velocity andtangential acceleration of P.
What is the linear velocity?
What is the tangential acceleration? Â Â
(c) At t = 2.45 s, find the position of P (in degrees, withrespect to the positive x-axis).
what is the answer ° counterclockwise from the +x-axis?
