Alocomotive is pulling 8 freight cars, each of which is loaded with the same amount of weight. the mass of each freight car (with its load) is 37,000 kg. if the train is accelerating at 0.48 m/s2 on a level track, what is the tension in the coupling between the second and third cars? (the car nearest the locomotive is counted as the first car, and friction is negligible.)

106560 N

Explanation:

Given

Let Tension between  2 and 3 car be and between 3 &4 is

mass of freight car =37,000 kg

acceleration of car

is accelerating all freights behind 3

therefore

Thus

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.
