Question

In Jerome's physics class, he had to solve the equation 40 = 12mv2 for m. Each step of his work is shown below.

Answer 1

Answer:

Step-by-step explanation:

I think you mean 1/2 for 12. I will assume so

40 = (1/2) m v^2                Multiply both sides by 2

40*2 = (1/2)*2  *m * v^2    Combine the 2s cancel.

80 =  m * v^2                    Divide by v^2

80/v^2 = m * v^2/v^2       Cancel

80/v^2 = m

Since I don't have the drop down menus, you'll have do the matching.
