Problem 1.372

What work has to be performed in order to increase the velocity of a particle of rest mass \(m_{0}\) from \(0.60 c\) to 0.80 c? Compare the result obtained with the value calculated from the classical formula.

Reveal Answer
A=0.42 m0c2 instead of 0.14m0c2A=0.42 \mathrm{~m}_{0} c^{2} \text { instead of } 0.14 m_{0} c^{2}
