The **momentum **of a **proton **would be:

(a) For particle moving with **speed **0.010c

p = 5.016 × 10^(-21) kgms^{-1}

p = 9.398 MeV/c

(b) For particle moving with **speed **0.50c

p = 2.89 × 10^(-19) kgms^{-1}

p = 541.5 MeV/c

(c) For particle moving with **speed **0.90c

p = 23.73 × 10^(-19) kgms^{-1}

p = 4446.35 MeV/c

For given question,

We need to calculate the **momentum **of a proton moving with a given speed.

We know that, the equation for** relativistic momentum** is,

We know, the **mass **of **proton **(m) = kg

(a) For particle moving with **speed **0.010c

v = 0.010c

the **momentum of a proton** would be,

(b) For particle moving with **speed **0.50c

v = 0.50c

the** momentum of a proton** would be,

(c) For particle moving with **speed **0.90c

v = 0.90c

the** momentum of a proton** would be,

Now, we need to convert answers into MeV/c

1 MeV = 1.6 × 10^(-13) kg.m²/s²

⇒ 1 kg.m²/s² = 625 × 10^(10) MeV

1 c = 299,792,458 m/s

⇒ 1 m/s = 3.3356E-9 c

So, 1 kg. m/s = 1.8737259e+21 MeV/c

(a) For p = 5.016 × 10^(-21) kgms^{-1}

⇒ p = 5.016 × 10^(-21) × 1.8737259e+21

⇒ p = 9.398 MeV/c

(b) For p = 2.89 × 10^(-19) kgms^{-1}

⇒ p = 2.89 × 10^(-19) × 1.8737259e+21

⇒ p = 541.5 MeV/c

(c) For p = 23.73 × 10^(-19) kgms^{-1}

⇒ p = 23.73 × 10^(-19) × 1.8737259e+21

⇒ p = 4446.35 MeV/c

Therefore, the **momentum **of a **proton **would be:

(a) For particle moving with **speed **0.010c

p = 5.016 × 10^(-21) kgms^{-1}

p = 9.398 MeV/c

(b) For particle moving with **speed **0.50c

p = 2.89 × 10^(-19) kgms^{-1}

p = 541.5 MeV/c

(c) For particle moving with **speed **0.90c

p = 23.73 × 10^(-19) kgms^{-1}

p = 4446.35 MeV/c
