A man cylces up a hill whose slope is 1 in 25 at `6 kmh^(-1)` . The mass of the man and the cycle is 150 kg . Find the power.

A man cycles up a hill whose slope is 1 in 20 with a velocity of 6.4 km h^(-1) along the hill. The weight of the man and the cycle is 98kg. What work per minute is the man doing ? What is his horse power ?

A boy climbs up a hill, which rises 1 in every 25, on his bicycle. The mass of the boy and his bicycle is 120 kg. What is the power applied by the body if he is cycling at the rate of 6 km/h hour? (Assume the friction is absent and g=10m//s^(2) )

A man is riding on a cycle with velocity 7.2(km)/(hr) up a hill having a slope 1 in 20. The total mass of the man and cycle is 100kg. The power of the man is

A man cycling up a smooth inclne road, climbs the road at a constant spped of 2m/s. The total mass of the man and the cycle is 150 kg and the inclination of the road with the horizonal is 30^(@) . What is the minimum horse power spend by the man? [Take g=10m//s^(2) and 1 horse power =750 watt]

A boy is cycling with a speed of 10 km h^(-1) on a hill of slope 1/20 . The weight of the boy and the cycle is 120 kg . Calculate the work done by the man per minute . Also find his horse power .

A trolley is being up an incline plane by a man inside the trolley He applied a force of 500 N. If the mass of the man is 50 kg and trolley is 150 kg, then the acceleration of the trolley will be : ( g = 10 m//s^(2) )

There is a man of mass 100 kg sitting on a motorbike of mass 150 kg. The distance of the axles of the wheels (wheelbase) is 1 . 5 m, the common mass center of the man and the motorbike is at a 1 m height above the ground level, and at a 0.6 m distance from the vertical line going through the rear axle. What normal force is exerted on the real wheel by the ground, when the motorbike starts off with an acceleration of a = 2 m//s^(2) ?

There is a man of mass 100 kg sitting on a motorbike of mass 150 kg. The distance of the axles of the wheels (wheelbase) is 1 . 5 m, the common mass center of the man and the motorbike is at a 1 m height above the ground level, and at a 0.6 m distance from the vertical line going through the rear axle. What acceleration is needed to lift the front wheel?

A man cycles up a hill rising 1 metre vertically for every 50 metres along the slope. Find the power of the man, if he cycles up at the rate of 3.6 km/ hr. The weight of the cycle and man is equal to 120kg. Neglect force of friction.

A man of mass 40kg is at rest between the walls as shown in the If '●' between the man and the walls is 0.8 find the normal reactions exerted by the walls on the man .
