Hi, your question was incomplete, hence I am writing down the complete question below.
Q)The displacement x of a particle of rest mass m0, resulting from a constant force m0g along the x-axis, is
x= c2/g{[1+(gt/c)2]power0.5-1}
including relativistic effects. Find the displacement x as a power series in time t. Compare with the classical result.
