A 40.0-cm diameter disk rotates with a constant angular acceleration of 2.80 rad/s². It starts from rest at t=0, and a line drawn from the center of the disk to a point Pon the rim of the disk makes an angle of 57.3° with the positive x-axis at this time. (a) At t - 2.40 s, find the angular speed of the wheel. x Your response differs from the correct answer by more than 10%. Double check your calculations, rad/s (b) Att 2.40 s, find the magnitude of the linear velocity and tangential acceleration of P. linear velocity tangential acceleration Your response differs from the correct answer by more than 10%. Double check your calculations. m/s x Your response differs from the correct answer by more than 10%. Double check your calculations, m/s? (c) At t= 2.40 s, find the position of P (in degrees, with respect to the positive x-axis). counterclockwise from the +x-axis
