The value of m will be (mV₂ + Mv₂)/V₁ so Brenna's equation is absolutely correct.
What is the equation?
A formula known as an equation uses the same sign to denote the equality of two expressions.
An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
Given,
mv₁ = (m + M)v₂
By multiplication on the right-hand side
mv₁ = mv₂ + Mv₂
Divide v₁ on both side
mv₁/v₁ = ( mv₂ + Mv₂)/v₁
m = (mV₂ + Mv₂)/V₁
Hence Brenna's solution is correct for the equation.
