How much work has to be done on a proton to accelerate it for thefollowing cases

Question

How much work has to be done on a proton to accelerate it for thefollowing cases. (a) from rest to 0.06c
1 MeV

(b) from 0.8c to 0.81c
2 MeV

(c) from 0.9c to 0.91c
3 MeV

(d) from 0.99c to c(Select all that apply.)
4 It isnot possible to increase the speed to c.
Infiniteenergy source would be required.
Noenergy is required.
Einsteintheorized that this would happen spontaniously.

Explanation / Answer

Formula :       K = mc2( -1) Where = 1 / (1-2) =1 /(1-(v/c)2) mass of proton m = 1.67 x 10-27 kg Therefore workdone = Kf - K1 Initial kinetic energy = 0 So that Workdone = Kf   =mc2( - 1) Substitute values and solve. Initial kinetic energy = 0 So that Workdone = Kf   =mc2( - 1) Substitute values and solve.
