Answer to Problem 65QAP

Einsteinian momentum =1.35×1022kgm/s

Explanation of Solution

Calculation:

An electron (mass, m=9.11×1031kg ) travels at v = 0.444c. The magnitude of theEinsteinian momentum is p=γmv, where γ=11 v2 c2 , The total energy E of the electronis the sum of its Einsteinian kinetic energy Kand the energy not associated with its motion,i.e., its rest energy, E0. The rest energy is equal to E0=mc2, and its total energy is equal to E=γmc2.

Relativistic gamma:

  γ=11 v2 c2 =11 (0.444c)2 c2 =1.116

  p=γmv=1.116×9.11×1031×0.444×3×108=1.35×1022kgm/s

Conclusion:

Einsteinian momentum =1.35×1022kgm/s

Answer to Problem 65QAP

Einsteinian kinetic energy =9.51×1015J

Explanation of Solution

Calculation:

  K+E0=EK=EE0=γmc2mc2=(γ1)mc2=(1.1161)×9.11×1031×(3×108)2=9.51×1015J

Einsteinian kinetic energy =9.51×1015J

Conclusion:

Einsteinian kinetic energy =9.51×1015J

To determine

(c)

Answer to Problem 65QAP

Rest energy =8.20×1014J

Explanation of Solution

Calculation:

  E0=mc2=9.11×1031×(3×108)2=8.20×1014J

Einsteinian kinetic energy =9.51×1015J

Conclusion:

Rest energy =8.20×1014J

To determine

(d)

The total energy of the electrontravels at 0.444c?

Expert Solution

Answer to Problem 65QAP

The total energy =9.15×1014J

Explanation of Solution

Calculation:

  E=γmc2=1.116×9.11×1031×(3×108)2=9.15×1014J

The total energy =9.15×1014J

Conclusion:

The total energy =9.15×1014J
