Problem
An astronaut lifts off from planet Zuton in a spaceship. The free-fall acceleration on Zuton is four times less than on the Earth. At the moment of liftoff the acceleration of the spaceship is 2.45 m/s² (up). The weight of the astronaut at that instant is more than her weight on the surface of the earth by the factor of:
(a) 4
(b) 2
(c) 1
(d) 0.5
(e) 0.25
