Hi there!
v = ±[tex]\sqrt{\frac{2K}{m} }[/tex]
- - - - - - - - -
K = 1/2mv²
Isolate for the variable "v". We can begin by dividing both sides by 1/2. (Multiply by the reciprocal, or 2):
2 · K = 2 · (1/2mv²)
2K = mv²
Continue isolating by dividing both sides by "m":
2K / m = v²
Take the square root of both sides. Remember that the solution can either be positive or negative since there are positive and negative roots.
v = ±[tex]\sqrt{\frac{2K}{m} }[/tex]
Answer: v = −√2Km/m
________________________________
Isolate the variable by dividing each side by factors that don't contain the variable.
Hope this helps!
