Question:

In Einstein’s theory of special relativity the mass of an object moving with velocity v is

m = mo 1 - 0/0


where m0 is the mass of the object when at rest and c is the speed of light. The kinetic energy of the object is the difference between its total energy and its energy at rest:

K = mc - moc

(a) Show that when v is very small compared with c, this expression for K agrees with classical Newtonian physics: K = 1/2m0v2 

(b) Use Taylor's Inequality to estimate the difference in these expressions for K when |v| ≤ 100 m/s.
