Textbook Problem

Find the velocity of a proton that has a momentum of 4.48 × 10 19 kg m / s .

To determine

The velocity of the proton.

Explanation

Given info:

  • The momentum of the proton is 4.48×1019kgms-1.

Formula used:

Formula to find the relativistic momentum is,

  p=m0v1v2c2

Here, vis the velocity of the electron, m0is the mass of the electron and cis the speed of light.

Rearranging the equation to find the expression for v,

  p2=m2v21v2c2p2=m2v2c2c2v2v2=p2c2m2c2+p2

Calculation:

Substituting the given values, we get,

  v2=(4.48×1019kgms-1)2×(3×108ms-1)2(1
