70 kg Its mass does not alter. Even if you consider "relativistic mass" ( which is now discredited) the magnitude of any such effect is negligible compared to the accuracy quoted of just 2 significant figures.

As the terminal velocity for earth is 53 m/s, by γ = 1/ √(1 − v^2/c^2)
=>γ = 1/ √{1 − (53)^2/(3 x 10^8)^2}
=>γ = 1.0000000000000312111111111120852Now by m = γm0, where
=>m = 1.0000000000000312111111111120852 x 70
=>m = 70.000000000002184777777777845967 kg
