Question

V = mv1/[M + M]? #Solve for m

Answer 1

see a solution process below;

Explanation:

Since we are asked to solve for `m` it thens mean that we have to look for the subject formula of `m`

`V = (mv1)/[M + M]`

First, we have to simplify the equation;

`mv1 = mv, (mv xx 1 = mv)`

`M + M = 2M, (1M + 1M = (1 + 1)M = 2M)`

Now we are having;

`V = (mv)/(2M)`

Secondly, cross multiplying both sides..

`V/1 = (mv)/(2M)`

`V xx 2M = mv xx 1`

`2MV = mv`

To get `m` standing alone, we have to divide it with its coefficient, in this case `v` is the coefficient..

Divide both sides by `v`

`(2MV)/v = (mv)/v`

`(2MV)/v = (mcancelv)/cancelv`

`(2MV)/v = m`

`:. m = (2MV)/v`

Hope this helps!
