Assertion : When a bicycle is in motion, the force of friction exerted by the ground on the two wheels is always in forward direction. Reason : The frictional force acts only when the bodies are in contact

A Wheel has circumference C. IF it makes f r.p.s, the linear speed of a point on the circumference is

Solve the following problrms using two variables: The fore wheel of a tractor makes 120 revolutions more than the rear wheel in going 720 m. If the diameter of the fore wheel is doubled and the diameter of the rear wheel is increased by 1 1/2 times the present diameter, then the fore wheel makes 20 revolution more than the rear wheel in going the same distance . Find the circumference of each wheel.

A car wheel 60 cm in diameter is turning at 8 revolutions per second. Then the car begins to slow uniformly to rest in a time of 14 seconds. Distance travelled by the car in this time is

The forewheel of a carriage makes 6 revolutions more than the rearwheel in going 120 m. If the diameter of the forewheel be increased by 1/4 its present diameter and the diameter of the rearwheel be increased by 1/5 of its present diameter, then the forewheel makes 4 revolutions more than the rearwheel in going the same distance. Find the circumference of each wheel of the carriage.

A wheel is 0.25m in radius . When it makes 15 revolutions per minute, its linear speed at a point on circumference is

The wheel of a car rotating with certain angular velocity is stopped in 7 seconds and before it stops, it makes 35 revolutions. Then initially it was rotating with the frequency.

A 2 m long ladder of mass 10 kg is kept against a wall such that is 1.2 m. away from the wall. The wall is smooth but the ground is rough. Roughness of the ground is such that it offers a maximum horizontal resistive force (for sliding motion) half that of normal reaction at the point of contact. A monkey of mass 20 kg starts climbing the ladder. How far can it climb along the ladder? How much is the horizontal reaction at the wall?

If a point on the circumference of a wheel having diameter 4 m has velocity of 1600 c m//s , then the angular velocity of the wheel will be
