An airplane propeller rotates 1000 times per minute. Find the number of degrees that a point on the edge of the propeller will rotate in 1 second.

The rotation rate of a mixing blade, in rotations per second, slows as a liquid is being added to the mixer. The blade rotates at 1,000 rotations per second when the mixer is empty. The rate at which the blade slows is four rotations per second less than three times the square of the height of the liquid. If h is the height of liquid in the mixer, which of the following represents R(h), the rate of rotation?

A wheel is rotating 300 times per minute. The angular velocity of the wheel in rad cdot s^(-1) unit is

A flywheel of moment of inertia 10^(7) g cm^(2) is rotating at a speed of 120 rotations per minute. Find the constant breaking torque required to stop the wheel in 5 rotations.

A car is moving from rest, After 10 seconds its wheels rotate 360 times in 1 minute. If the radius of the wheel is 50cm, then find the linear distance travelled in 6 minutes.

A rigid body is rotating about a vertical axis at n rotations per minute, If the axis slowly becomes horizontal in t seconds and the body keeps on rotating at n rotations per minute then the torque acting on the body will be, if the moment of inertia of the body about axis of rotation is I.

The blades of an aeroplane propeller are 2m long and rotate at the rate of 300rpm Calculate (i) the frequency (ii) the period of rotation (iii) the angular velocity (iv) the linear velocity of a point 0.5m from the tip of the blade .
