Question

Question:
A disk is originally rotating at omega-zero equals 12 radians per second. It is subjected to a constant angular acceleration of alpha equals 20 radians per second squared. Determine the magnitudes of the velocity and the normal and tangential components of acceleration of point B when the disk has undergone 2 revolutions. Point B is located at a radius of 0.4 meters from the center.

Planar Kinematics of a Rotating Disk: Velocity and Acceleration of a Point

This lesson applies rotational kinematics to find the angular velocity of a disk after a given angular displacement, then uses the rigid-body relationships to determine the speed and the normal and tangential acceleration components of a point on the disk. The method combines the kinematic equation $\omega^2 = \omega_0^2 + 2\alpha\theta$ with the point-a
