## Homework Statement

station has radius 25m and rotate with w.

we were asked to find the period of rotation required to produce apparent gravity 0.7g i worked this out to be 11.99s = 12s. using a(0.7g) = v^2 /r

we are then asked if astronaut weighs 75Kg and runs at 5m/s in the direction of rotation what is his apparent weight?

## The Attempt at a Solution

I know the weight will increase but I am not sure by how much

i tried finding the coriolis acc. = 2wv' v' is velocity in rotating frame

this is relative to the centrifugal force (which in this case is 0.7g) so i divided by this amount and got:

2*2pi/12*5 = 5.24m/s/s

5.24/0.7g = 0.763

i was wondering if this means that the weight increases by 76% so it changes from:

before = 75*0.7g = 515.025N

after = 907.98N

i thought this might be too much but then again he is running at 5m/s

is this right?
