If a =87.5 kgm=87.5 kg person were traveling at =0.=0.900c , where is the speed of light, what would be the ratio of the person's relativistic kinetic energy to the person's classical kinetic energy?

Explanation:

Given:

mass, m = 87.5kg

Velocity, V = 0.900c

now,

the relativistic kinetic energy id given as:

...........(1)

where,

= relativistic factor, given as;

Now, the classical kinetic energy is given as:

   ..........(2)

Dividing the equation (1) by (2) we get

or

substituting the values in the equation we get,
