`m=(M)/(sqrt(1-(v^(2))/(c^(2)))`
The equation above describes, according to Einstein's theory of relativity, how the mass of an object increase with velocity where m is the mass of moving object, M is the mass the mass the object when it is not moving, v is the velocity of the object relative to a stationary observer, and c is the speed of light. Which of the following expresses v in terms of m, M, and c?
