$A$ wheel rotates with a constant acceleration of $2.0 \ rad/s^2$. If the wheel starts from rest,the number of revolutions it makes in the first ten seconds is:

What is the value of the tangential component of the linear acceleration of a particle of a rigid body rotating with a constant angular velocity?

The ratio of the angular speed of a second-hand to the hour-hand of a watch is (in $: 1$)

$A$ wheel rotates with a uniform angular acceleration of $2.0 \ rad/s^2$. If the wheel starts from rest,the number of revolutions completed in the first $10 \ s$ will be approximately:

The direction of angular acceleration of a body moving in a circle in the plane of the paper is

$A$ car is moving at a speed of $72 \, km/h$. The diameter of its wheels is $0.25 \, m$. If the wheels stop after completing $20$ revolutions upon applying brakes,the angular retardation produced by the brakes is ....... $rad/s^2$. (in $.5$)
