21. The force F acting on a body with mass m and velocity v is
the rate of change of momentum: F = (d/dt)(mv). If m is
constant, this becomes F = ma, where a = dv/dt is the
acceleration. But in the theory of relativity the mass of a
%3D
particle varies with v as follows: m = mo//1 – v²/c²,where
mo is the mass of the particle at rest and c is the speed of
light. Show that
moa
F =
(1 – v²/c?)/2
