4.333333 kilometers an hour
Answer: D) none of the above
Explanation: This is a classic problem of thermodynamics, and refers to the principle of conservation of energy to give a correct answer
Option A) can be ruled out since no matter how much friction is reduced, it will always exist and therefore some energy will be lost
option B) and C) are out of context since the loss of work or energy will continue to exist even if those values are modified, so they do not answer the question
D) is the correct one since it should be said that this is not possible (so far...) as it goes against the conservation of energy and this option is none of the above
It's c/f, in which c is the speed of light (300000 m/s)
Speed is scalar, meaning it's only going to be like 74 mph, doesn't matter which direction. Velocity is a vector, meaning it has direction. You can go -74mph when talking about velocity, not speed.
