A disk rotates with constant angular acceleration

Reference no: EM13681583

A disk rotates with constant angular acceleration. The initial angular speed of the disk is 2 rad/s. After the disk rotates through 1 Radians, the angular speed is 17rad/s.

1) What is the magnitude of the angular acceleration?

2) How much time did it take for the disk to rotate through 1 radians?

3) What is the tangential acceleration of a point located at a distance of 6.4 cm from the center of the disk?
