This is the same as saying that v1/v2= r1/r2 as you have below.ZedCar said:Homework Statement
The unknowns below read as "m sub 1", "rub sub 2" etc.
The maths part of a physics problem states:
r1/v1 = r2/v2
If you meant to say "m1r1= m2r2" above, yes, that is correct.gives:
v1/v2 = r1/r2 = m2/m1
Thank you!
This is not an equation. Did you mean "m1r1= m2r2"?ZedCar said:Homework Statement

r1/v1 = r2/v2
Combining these with equation :
m1r1/m2r2
You have initially, r1/v1 = r2/v2. Multiply both v1/r2. On the left the "v1" terms cancel and you get (r1/v1)(v1/r2)= r1/r2 and on the right the "r2" terms cancel and you get (r2/v2)(v1/r2)= v1/v2 so v1/v2= r1/r2.gives:
v1/v2 = r1/r2 = m2/m1
Homework Equations
The Attempt at a Solution
Would anyone be able to explain to me how they have gone to the final line of
v1/v2 = r1/r2 = m2/m1
Thank you!

An algebraic unknowns problem is a mathematical problem that involves finding the value of unknown variables in an equation using algebraic methods. These problems typically include one or more equations with one or more unknown variables, and the goal is to solve for the values of those unknowns.
To solve an algebraic unknowns problem, you can use algebraic techniques such as simplifying, factoring, and substitution. Start by isolating one of the unknown variables in one of the equations, then use that value to substitute into the other equations until you have solved for all of the unknowns.
The most common types of algebraic unknowns problems include linear equations with one or two variables, systems of equations with two or three variables, and quadratic equations with one variable. These types of problems can be solved using different algebraic techniques and may have multiple solutions or no solution at all.
You can check your solution to an algebraic unknowns problem by plugging the values you found for the unknowns back into the original equations. If the equations are satisfied, then your solution is correct. You can also use a graphing calculator to graph the equations and see if the lines intersect at the values you found for the unknowns.
Yes, there are several strategies that can help you solve difficult algebraic unknowns problems. These include using a systematic approach, breaking the problem into smaller steps, and trying different algebraic techniques if one approach does not work. It can also be helpful to practice solving various types of problems to improve your problem-solving skills.
