Homework Statement
a person is standing stationairy on Earth (whilst it is rotating) there is a net force towards the centre of the earth.
What would the free body diagram look like.
Please could someone explain why
thanks
Homework Equations
I know the formula for acceleration (v^2/r) and Force = m(v^2/r).
The Attempt at a Solution
I would suggest that the free body digram shows:
R + mv^2/r = mg
so mv^2/r = mg-R
But I get really confused by R and mg as they should cancel out.
Please could someone explain it
