Question

Solve for M F=mv2/r this is a fraction btw and the 2 is an exponent

Answer 1

\[F= \frac{ mv^2 }{ r }\] ah good ole centripetal force, alright any idea how to begin?

Answer 2

no

Answer 3

i need help on these

Answer 4

Ok so what happens if you multiply both sides by r?

Answer 5

it turns to r?

Answer 6

???

Answer 7

is it mv^2?

Answer 8

\[\color{red}r F = \frac{ mv^2 }{ r } \color{red}{r}\] what happens to the r on the right side

Answer 9

uhh

Answer 10

turns to rf/v^2

Answer 11

Notice the r gets cancelled on the right, the idea is to get "m" on its own so when we do something to one side we have to do it to the other, or if you do it to the left side you must also do it to the right, then we're left with \[F r = mv^2\] now we have that v^2 what can we do?

Answer 12

fr/v^2

Answer 13

Yes!

Answer 14

thats the answer?

Answer 15

Sounds good!

Answer 16

\[m = \frac{ Fr }{ v^2 }\]

Answer 17

I got the answer right thanks
