In order to transfer energy to an object we need to exert a force on that object. And the amount of energy transferred by the force is called the word done by that force. And formula for work done is the dot product of force exerted on that object and displacement by that object. Finally is replace F=ma and a=1/2mv^2. We will find that work done is the difference between the final and initial value of kinetic energy. And this is known as work-energy principle. read less

A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is: A. 45 km/hr B. 50 km/hr C. 54 km/hr D. 55 km/hr
The relative velocity of train is (x-5) if x is real velocity. (x-5) *(1000/3600 )* 10 = 125 x = 50km/hr
