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 you very much

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.

black lol

step-by-step explanation:

h

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.
