A useful equation for this decrease in g is g= a – bz, where z is the elevation above sea level, a = 9.807 m/s2, and b= 3.32 x 10-6 1/s2. An astronaut "weighs" 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z = 345 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the satellite stopped moving? The person's weight in N while floating around in the International Space Station is 691 N. The astronaut feels a gravitational acceleration of 9.807 m/s2.arrow_forward
