Did you know that human mass grows when moving fast enough? It becomes especially large if the speed approaches the speed of light [[$ 2.9979246\cdot10^8 $]] m / s. According to the theory of relativity, the increase in mass with increasing speed can be with the following the formula:

[[$ {new mass} = \displaystyle\frac {old mass} {\sqrt {1 – \displaystyle\frac {speed^2}{light speed^2}}} $]]

Calculate your mass if you were moving at speed of

a) [[$ 29 $]] m/s.

Answer: My mass would be

b) [[$ 290 $]] m/s.

Answer: My mass would be

c) [[$ 2.9 \cdot 10^8 $]] m/s.

Answer: My mass would be

d) [[$ 2.99 \cdot 10^8 $]] m/s

Answer: My mass would be

e) [[$ 2.9979 \cdot 10^8 $]] m/s

Answer: My mass would be

f) [[$ 2.9979245 \cdot 10^8 $]] m/s

Answer: My mass would be
