Question
Hello, can you help me for this physics question? Can you please also show me the diagram that I can understand quickly? Thanks a lot! A 1500kg vehicle runs on a natural gas engine. The vehicle travels a distance of 9km on an ascending (rising) slope with a drop of 50m. Under the action of the motor, the speed doubles (it goes from v1 to v2 = 2 * v1). It is then measured that 28g of natural gas has been burned. Assuming that the engine efficiency is 65% and that friction is neglected, calculate one of the two speeds of the vehicle. Hint: Start by calculating the energy supplied by the combustion of natural gas. The answer is 5.4%
