A constant force of 397 N acts on a spacecraft of mass 7880 kg that has an initial velocity of 31 m/s. How far has the spacecraft traveled when it reaches a velocity of 4880 m/s?

Explanation / Answer

a =F/m   = 397/7880 = 0.0504 m/s2

v^2 - u^2 = 2as

4880^2 - 31^3 = 2 x 0.0504 x s

s   = 2.362 x 10^8 m
