Total 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
I 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?
