Ram and Shyam are two fast friends since childhood. Shyam neglected studies and now has no means to earn money other than a camel whereas Ram becomes an engineer. Now both are working in the same factory. Shyam uses camel to transport the load within the factory.

Due to low salary & degradation in health of camel, Shyam becomes worried and meet his friend Ram and discusses his problem. Ram collected some data & with some assumptions concluded the following: The load used in each trip is 1000 kg and has friction coefficient = 0.1 and = 0.2. Mass of camel is 500 kg. Load is accelerated for first 50 m with constant acceleration, then it is pulled at a constant speed of 5 for 2 km and at last stopped with constant retardation in 50 m. From biological data, the rate of consumption of energy of camel can be expressed as where P is the power and v is the velocity of the camel. After calculations on different issues Ram suggested proper food, speed of camel etc. to his friend. For the welfare of Shyam, Ram wrote a letter to the management to increase his salary.The ratio of the energy consumed of the camel during uniform motion for the two cases when it moves with speed 5 m/s to the case when it moves with 10 m/s.
