In physics, Albert Einstein's famous formula for mass-energy equivalence defines an object's energy, Measured in joules ( j ) , n terms of its mass, m, measured in kilograms (KG) and the speed of light, c, measured in meters per second (ms)left parenthesis, m, slash, s, right parenthesis. The formula is commonly written as E = mc2.
Rearrange the formula to solve for the speed of light (c)
