Hello, so we have the two coaches, freshing or working in the opposite direction of motion.
00:13
Their masses given and they are coupled with tension t in their coupling.
00:18
The tension points away from the masses at each point.
00:22
One megaggram is 10 to the power 6 grams, which is 10 to the power 6 of 10 minus 3 kilograms.
00:29
So that is 10 to the power 3 kilograms.
00:31
And then fission is given.
00:32
So we apply nitty and second law to each of the masses.
00:37
For the first mass, tension is in our choosing direction of motion.
00:42
Fration is opposing so we subtract friction.
00:45
The net force is equated to the mass a times its acceleration.
00:49
It is the mass of a.
00:50
Likewise for b, this time both friction and tension are opposing direction of motion...
