Horse power = ______________.

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]

An elevator that can carry a maximum load of 1500 kg (elvator+ passengers) is moving up with a constant speed of 2 ms^(-1). The frictional force opposing the motion is 3000 N. Find the minmum power delvered by the motor to the elevator in watts as well as in horse power (g=10ms^(-2))

In a motor the electrical power input is 500 W and the mechanical power output is 0.54 horse power. Heat developed in the motor in 1 h is (assuming that all the electric energy which is not converted to mechanical energy is converted to heat) is

The force required to row a boat over the sea is proportional to the speed of the boat. It is found that it takes 24 h.p. to row a certain boat at a speed of 8km/hr, the horse power required when speed is doubled -
