The energy, E, of a body of mass m moving with speedv is given by the formulaE = mc211
Chapter 14, Problem 47(choose chapter or problem)
The energy, E, of a body of mass m moving with speedv is given by the formulaE = mc211 v2/c2 1.The speed, v, is nonnegative and less than the speed oflight, c, which is a constant.(a) Find E/m. What would you expect the sign ofE/m to be? Explain.(b) Find E/v. Explain what you would expect thesign of E/v to be and why.
