The astronaut's apparent weight during take off is the same as their actual weight, since during the take off, the rocket and the astronaut experience the same acceleration. This means that the astronaut's apparent weight is 56.3 kg.
Apparent weight is the force which the support (such as floor, chair, etc.) exerts on a body. The force is caused due to the acceleration applied to the body due to gravity or any other means. Since the astronaut is inside a rocket which is accelerating, the apparent weight is the same as the actual weight of the astronaut.
