The angular speed of a geostationary satellite is equal to the angular speed of:

If the friction available is insufficient to provide the centripetal force while a car turns on a level road, the car will:

A stone of mass 0.3 kg is whirled in a vertical circle of radius 0.5 m at a constant speed of 5 m/s. The difference between the tensions at the bottom and at the top is (g = 10 m/s^2):

A rotating body conserves its angular momentum L = mvr. If the radius of rotation decreases to half with angular momentum conserved, its speed becomes:

Centrifugal force is an example of:

A car of mass 1000 kg takes a level turn of radius 100 m at a speed of 20 m/s. If the maximum friction available between the tyres and the road is 3000 N, the car will:
