Human Metabolism

Being described as the most complicated machine ever encountered by humans, the human body and the cell metabolism is nothing less than a wonder. Metabolism is the set of life-sustaining chemical reactions within organisms.

A crate of fruit with a mass of 40.0 kg and a specific heat capacity of 3550 J/(kg. K) slides 9.00 m down a ramp inclined at an angle of 40.0 degrees below the horizontal. Part A If the crate was at rest at the top of the incline and has a speed of 2.55 m/s at the bottom, how much work Wf was done on the crate by friction? Use 9.81 m/s² for the acceleration due to gravity and express your answer in joules. ► View Available Hint(s) Wf = -2140 J Submit Correct The frictional force opposes the motion of the crate, so the work done on the crate by friction must be a negative quantity. Part B Previous Answers If an amount of heat equal to the magnitude of the work done by friction is absorbed by the crate of fruit and the fruit reaches a uniform final temperature, what is its temperature change AT? ► View Available Hint(s) AT = ΑΣΦ W
