The relativistic momentum of a 1000 kg car moving at 0.95 times the speed of light is A) 9.13x10⁸ kg m/s B) 9.13x10¹¹ kg m/s C) 3200 kg m/s D) 2.85x10¹¹ kg m/s

Question

Quizplus · Accepted Answer

The relativistic momentum is given by $p = \frac{mv}{\sqrt{1 - \frac{v^2}{c^2}}}$, where $m$ is the rest mass, $v$ is the velocity, and $c$ is the speed of light. For a car with a mass of 1000 kg moving at 0.95c, the denominator becomes very small, significantly increasing the momentum. This results in a much larger value than the classical momentum, which matches the magnitude given in option B.
