The graph shown in the figure represents

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 5m/s 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. Maximum power transmitted by the camel to load is–

The ratio of magnitude of work done by camel on the load during accelerated motion to retarded motion is–

A ball is released from point A as shown in figure. The ball leaves the track at B. All surfaces are smooth. Let h be the maximum height from ground reached by ball after leaving track at B. Then If track makes an angle with horizontal at B then maximum height attained by ball will be :

If the lines and represent three consecutive sides of a rectangle then ab

Hence ab=18
Choice 1 is correct

   The product obtained in this reaction is

A ball is dropped on a floor and bounces back to a height somewhat less than the original height, which of the curves depicts its motion correctly?
