IP In Conceptual Checkpoint 29-2 we considered an

Chapter 29, Problem 90GP

(choose chapter or problem)

The rest energy, \(m_{0} c^{2}\), of a particle with a kinetic energy  and a momentum  can be determined as follows:

\(m_{0} c^{2}=\frac{(p c)^{2}-K^{2}}{2 K}\)

Suppose a pion (a subatomic particle) is observed to have a kinetic energy \(K=35.0 \mathrm{MeV}\) and a momentum \(p=5.61 \times 10^{-20} \mathrm{~kg}^{3} \mathrm{~m} / \mathrm{s}=105 \mathrm{MeV} / \mathrm{c}\). What is the rest energy of the pion?

m0c2

m0c2=(pc)2 - K2 over 2K

K=35.0MeV

p=5.61 x 10-20 kg3 m/s=105MeV/c
