Answer:
32 pounds
Explanation:
The amount of water in the 200 pound person is
200 * 60% = 200*0.6 = 120 pounds
Of the 120 pounds, a third of this is extracellular fluid, the amount of extracellular fluid is
120 / 3 = 40 pounds
20 % of this is in the blood, which amounts to
40 * 20% = 40 * 0.2 = 8 pounds
The rest is interstitial fluid, which is
40 - 8 = 32 pounds
10Km South. Displacement is the total distance the subject is from the starting point.
Gravity?????????? or maybe like any object
If he moves the piano 4 meters, with 700 newtons of force
in the direction of the motion, then the work done is
Work = (force) x (distance)
= (700 N) x (4 m) = 2,800 joules .
If he does all of that in 2 seconds, then
he did it at the rate of
(work) / (time) = (2,800 J) / (2 sec) = 1,400 watts
(about 1.88 'horsepower' !)
