Question

How much force does an 71 {\rm kg} astronaut exert on his chair while sitting at rest on the launch pad?
Express your answer using two significant figures.

Answer 1

They need to tell you how much his space suit weighs, unless the astronaut is naked. Suits are heavy. It would also depend upon whether his feet were on the ground or not, while sitting.

Since he is at rest, he'd get the sme weight reading that he would on a scale outside the rocket.

Answer 2
