to rotate about an axis passing through its center and perpendicular to the plan

Question

to rotate about an axis passing through its center and perpendicular to the plane of the disk. If the disk starts with an angular velocity of 6.0 rad/s and is subject to a constant for 10 s. (Assume the positive direction is in the initial direction of the rotation of the disk. Indicate the direction with the sign of your answer.) angular acceleration of 8.0 rad/s2, find the angular displacement of a point on the rim of the disk as it rotates under these conditions rad Additional Materials O - points TAM 1 6 POST.002. A uniform disk is constrained to rotate about an axis passing through its center and perpendicular to the plane of the disk. You are given the following equation of angular motion for the rotating disk Assume ? is in rad and t is in s. Assume the positive direction is in the initial direction of rotation of the disk indicate the director with the sig of your answer.) ee) -1.5+(6.49 (a) What is the initial angular position of the point on the disk described by this equation? rad (b) What is the angular velocity of the disk at t0 rad/s (c) What is the angular acceleration of the disk? rad/s

Explanation / Answer

Solving 1st question

wi=Initial angular speed=6 rad/s

a=angular acceleration=8rad/s^2

Let the angular displacement is S

S=wi*t+0.5*a*t^2

S=460 radian
