Question

Einstein's formula for relativity is E = mc2 where E = energy, m = mass, and c = the speed of light.

Solve E = mc2 for c

a) c= square root of quantity E over m

b)c = E over m

c) c = square root of quantity m over E

d) c = m over E

Answer 1

E = mc^2

To solve the equation for c,

• divide both sides by m,

then

• take the square root of both sides

Answer 2

can you show me how to do it.. like a visual example?

Answer 3

if you instead had

F = kx^2

and were solving for x


F/k = kx^2/k (dividing both sides by k)
F/k = x^2 (simplifying the right hand side)

√(F/k) = √x^2 (taking the square root )

√(F/k) = x (simplifying the right hand side)

x= √(F/k) (answer)

Answer 4

Your first step is to divide both sides by m

E = mc^2


. . .

Answer 5

so A is the answer?
