Hello all,
Need some help with this question:
You stand on the seat of a chair and hop off.
a) During the time you are in flight down the floor, the Earth is lurching up toward you with an acceleration of what order of magnitude? In your solution explain your logic. Model the Earth as a perfectly solid object.
b) The eath moves up through a distance of what order of magnitude?
what I did for part (a):
I figured that the order of magnitude would be in the opposite direction when the falling mass hits the earth. I also figured I could use this equation:
F=ma
SO I think I have to solve for acceleration. I know the mass of the sun (5.98 x 10^24). But I'm missing force and acceleration (is acceleration the gravity in this case?)
a little stuck at this point.
what I did for part (b):
I used the same equation but to no avail. Can anyone help explain this to me? thanks!
