1. The formula E-1/2mv^2 is often used in science where E is the kinetic energy of the object, m is the mass of the object and v is the seed of the object. Which equation finds m given E and v?
A. m=2E+v2
B. m=E2v2
C. m=E2v2
D. m=2Ev

My answer is C
look at B. and C.
You have typed up the same answer for both. Assuming your original was supposed to be E=1/2(mv^2) then...
The answer you need is m=2E/v^2 when you re-arrange to get m alone : )
So whichever is that one is the one you need : )

E = 1/2M*V^2.
2E = M*V^2,
M = 2E/V^2.
2E = M*V^2,
M = 2E/V^2.
