= Learning Goal: To learn to calculate energy and momentum for relativistic part

Question

= Learning Goal: To learn to calculate energy and momentum for relativistic particles and, from the relativistic equations, to find relations between a particle^'s energy and its momentum through its mass. The relativistic momentum /vecp and energy E of a particle with mass m moving with velocity /vecv are given by /vecp = / fracm/vecv/sqrt1 - /fracv^2 c^2 and E = / fracmc^2/ sqrt1 - /fracv^2c^2. Part C What is the value of the expression E^2 - (pc)^2 for this proton? Express your answer in millions of electron volts squared to three significant figures.

Explanation / Answer

E^2-(pc)^2= m^2*c^4

mass of proton= 938 Mev/c^2
so
required value will become 938^2 Mev
