Question

Make v the subject of the relation KE = ½mv²

Answer 1

Answer:

v=√(2KE/m)

Step-by-step explanation:

KE=1/2mv^2

2KE=mv^2

(2KE)/m=v^2

sqrt[(2KE)/m]=v

v=√(2KE/m)

Answer 2

Answer:

$v=\sqrt{\frac{2KE}{m} }$

Step-by-step explanation:

$KE = 1/2mv^2$

$KE/1/2=mv^2$

$2KE=mv^2$

$2KE/m=v^2$

$\sqrt{2KE/m} =v$
