K 1 2mv 2

k = 1 / 2mv

You want to place everything on the right with v on the left. First multiply both sides by 2 (to count 1/2)

2k = mv 2

Divide both sides by m.

2k / m = v 2

Make a square root on both sides. Remember there are two options because this is the square root.

+ (Square root) (2k / m) = v

If you need to leave the denominator, you have to make the left side with (square) m / (square) m. Race

+ ((Square) 2 km) / m = v

2 k = mv Â,

v ‚² = 2 k / m

v = Â ° (2k / m)

k = 1 / 2mv 2

Times 2

2k = mv 2

(2k) / m = v 2

 ° (2k) / m = v
