How much work must be done on a particle with a mass of mm to accelerate it from rest to a speed of 0.084 cc ? (Express the answer in terms of mc2mc2.)

Work = 0.68 mc²

Explanation:

given data

speed = 0.084 cc

solution

as kinetic energy of mass particle is

KE = mc²( - 1 )  ............1

here is lorentz constant

=    

=    

=  1.68

as here particle start from rent so initial KE is 0

and final KE = mc²(1.68 - 1 )

final KE = 0.68mc²

so here work done to increase speed of particle

W = final KE - initial KE

Work = 0.68 mc²

explanation:

i tried it and took the test

if im wrong then we have different tests
