Adisk with a radius of 0.1 m is spinning about its center with a constant angular speed of 10 rad/sec. what are the speed and magnitude of the acceleration of a bug clinging to the rim of the disk?

The speed of the bug at the rim of the circular disk is and the acceleration of the bug is .

Further Explanation:

Given:

The angular velocity of the disk is .

The radius of the circular disk is .

Concept:

The linear speed of the bug present at the rim of the circular disk is given by.

Here, is the linear speed, is the radius of the disk and is the angular speed of the disk.

Substitute for and for in above expression.

The magnitude of the centripetal acceleration of the bug cling to the rim of the disk is given as.

Substitute for and for in above equation.

Thus, the speed of the bug at the rim of the circular disk is and the acceleration of the bug is .
