question 102

Short Answer

An alpha particle has a mass of $6.64 \times 10 ^ { - 27 } \mathrm {~kg}$ and a charge of $3.20 \times 10 ^ { - 19 } \mathrm { C }$ , and it is traveling at $\left. 0.9650 \mathrm { c } . \left( c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } \right) , 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J} \right)$
(a) What is its rest energy (in $\mathrm { GeV }$ )?
(b) What is its total energy (in $\mathrm { GeV } )$ ?
(c) What is its kinetic energy (in GeV)?
