Question

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

Use the drop-down menus to explain each step.


CLEAR CHECK
Given Equation: 40 = 12mv2

Step 1: 40v2 = 12m
on both sides of the equation.

Step 2: 80v2 = m
on both sides of the equation.

I need answer ASAP LIKE FAST PLAESE by the morning or before 9:00 thank you very much

Answer 1

the answeer is in the picture this is for egde

Answer 2

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.
