To find the relativistic momentum of protons accelerated to a kinetic energy of 470 MeV in a linear accelerator, we can use the formula p = √(2mE), where p is the momentum, m is the rest mass of the proton, and E is the kinetic energy. By substituting the given values into the formula, the relativistic momentum is found to be 6.82 x 10⁻¹⁹ kg m/s.

To find the relativistic momentum of protons accelerated to a kinetic energy of 470 MeV in a linear accelerator, we can use the formula:

p = √(2mE)

where p is the momentum, m is the rest mass of the proton (1.67 x 10⁻²⁷ kg), and E is the kinetic energy (470 MeV).

First, convert the kinetic energy to joules by multiplying it by the conversion factor:

1 MeV = 1.6 x 10⁻¹³ J

So, 470 MeV = 470 x 1.6 x 10⁻¹³ J = 7.52 x 10⁻¹¹ J

Now, substitute the values into the formula:

p = √(2 x 1.67 x 10⁻²⁷ kg x 7.52 x 10⁻¹¹ J)

Calculating the expression gives:

p = 6.82 x 10⁻¹⁹ kg m/s

Therefore, the relativistic momentum of the protons is 6.82 x 10⁻¹⁹ kg m/s.
