Question

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)

Answer 1

The formula for the speed of light is
`c= \sqrt{(E)/(m) }`

The speed of light is approximately 300,000,000 m/s

Explanation:

Answer 2

Begin by dividing both sides by m

`(E)/(m)=c^2` Take the square root of both sides.

`\sqrt{(E)/(m)}=√(c^2)` Evaluate the right

`\sqrt{(E)/(m)}=c`
