Yeah, I gave up on trying to change sides and just added in the variables then divided Ek by 1/2 and v to get m but thanks for helping. I'll remember to multiply by 2 to get rid of the 1/2 next time.
I'm doing my physics homework and for one of the questions i have to find m(mass) when i already know Ek(kinetic energy) and v(velocity) with the equation Ek=(1/2)mv^2. I was just wondering if someone could tell me how to move the m in front of the equal sign and to move Ek to the other side.
