**drwls**, Wednesday, December 12, 2012 at 11:10pmTotal energy is

E(rest) + E(kin)

= m*c^2/sqrt[1 - (v/c)^2]

Calculate that at each speed and take the difference.

(a) m*c^2/sqrt[1 - .19^2]

- m*c^2/sqrt[1 - .18^2]

= m*c^2[1.01855 - 1.01660]

= m*c^2* 1.95*10^-3

**Brian**, Thursday, December 13, 2012 at 12:38amI got 1*10^-16 but what's the unit for my answer? Because the book says 1.0 ke V is the answer for part (a). How do I get there?
