How much force does an 88 kg astronaut exert on his chair while sitting at rest on the launch pad?
Answer: 860N
Now the question: How much force does the astronaut exert on his chair while accelerating straight up at 14 m/s^2?
What do you do first, how do you go about getting the answer?

forceup= m*a+m*g

You can use F=m(a+g). So F=88(9.8+14)>2094.4N
