1. The problem statement, all variables and given/known data we have a spaceship with a spinning wheel artificial gravity thingy on-board with radius 25m, period ~ 12s, a=6.87 it is spinning anticlockwise if we take a perspective looking down on it (in the bottomleft is point A,bottom right point B,and at the top point C) an astronaut is running (like a hamster in a wheel) on the inside of this thing. find the astronauts (mass = 75kg) apparent weight if he runs in the direction ABC AND ACB. 2. Relevant equations centrifugal force F = -mw2r apparent force in rotating frame F=F(external) - F(centrifugal) V=r*w a = v*w w=2pi/T 3. The attempt at a solution external force = 75kg*6.87(angular acceleration of wheel) = 515.25N In direction ABC w = (angular velocity of wheel + extra angular velocity of antronaut running) = (0.52+0.2) = 0.72 so F(Centrif) = 75*(0.72)2*25 = 972 therfore astronauts weight = 515.25 - 972 this cant be right can it?
