Question

Could someone check my work? When I compare my answer to the textbook solution here on Chegg our answers are different by a factor of 10^10 MeV. Why am I getting 2.74*10^10 MeV when the Chegg textbook solution is 274 MeV? Who is right? Thanks 37.38 Creating a Particle. Two protons each with rest mass M 1.67 x 10 kg) are initially moving with equal speeds in opposite directions. The protons continue to exist after a colli- sion that also produces an no particle (see Chapter 44). The rest mass of the 9.75 x 10 kg. (a) If the two protons and the m are all at rest after the collision. find the initial speed of the protons, expressed as a fraction of the speed of light. (b What is the kinetic energy of each proton? Express your answer in Mev. (c) What is the rest energy of the mo. expressed in Mev? (d) Discuss the relationship between the answers to parts(b and c.

Explanation / Answer

Chegg textbook solution is absolutely correct.

Proton KE can't be 2.74x1010 Mev (very high value) at v=0.633c

=> 274 Mev is Right.
