How do I solve for delta m?

Question

divided thought by 2 pi and then both sides squared then *m1*g and then :(m2+delta m) ??? or first factor out and then -m2*s and at the end : by s so that delta m stands alone by the way the 0.66 belongs to it

rstroh · Answer

and then: (m2 + delta m)... Let's split through s and last -m2.

thought divided by 2 pi and then both sides square then *m1*g

so good. But then it says:

Then go on

On both sides divided by "s"
On both sides minus m ₂

Commentary: To understand the solution do not use the 0.66, but use the last equation:

Note : The rounding error of 0.33s or 0.66s is already so large that, when required (c), about 2447 kg are obtained when calculating at 0.66 s.

Look at my supplement in the answer. In comments you can't write any formulas.

may I ask how to write like this with break and so on

Once you write a question or answer, three points are at the top right. When you click on it, a formatting line appears and there is _{an x} labeled symbol. Then click on it and then a formula editor input line appears. You can put the formulas together.

Otherwise you can use LaTeX, which is a bit difficult to learn.

would never have come to the point that you both used only the right one but if you came to 2447 kg then my right only was to use because came to 2447 but thanks
