The radius of the front wheel of an engine is 35 cm and the radius of its behind wheel is 84 cm. How many more revolutions will revolve the front than the behind wheel to travel a distance of 600 m ?

The radius of the wheel of a train is 0.35 m. If the wheel rounds 450 times in one minute, then find the velocity of the train per hour.

If a cycle wheel of radius 4 m completes one revolution in two seconds, then acceleration of the cycle is.

A wheel turns 55 times to cover distance of 77 m. Let's calculate, how many revolution the whell will take to cover a distance of 98 m.

A cord of negligible mass is wound round the rim of a flywheel of mass 20 kg and radius 20 cm. A steady pull of 25 N is applied on the cord. The flywheel is mounted on a horizontal axis with frictionless bearings Find the kinetic energy of the wheel at this point when 2m of the cord is unwound. Assume that wheel starts from rest.

Two hands of a clock are of length 5 cm and 4 cm. How more distance the top of one of the hands will revolve than the top of the other hand in 2 days and 6 hours ?

The radius of base of a solid right circular iron - rod is 32 cm and the length of the rod is 35 cm . How many solid right circular cone of radius of base 8 cm and of height 28 cm can be made by melting this rod ?

The perimeter of a front sheel and rear wheel of an engine are 14 dcm. and 35 dcm respectively. Let’ find the minimum distance the engine can cover before both wheels take complete revolutions together
