Find the horizontal displacement due to the rotation of the earth if a body dropped from a fixed platform at a height (h) at the equator, neglecting the effects of air resistance. What is the displacement if h=5 km?

 

I would appreciate help with c-g :)

b. Write your available equations (in this case the three components of the
coriolis acceleration du/dt, dv/dt, dw/dt and the vertical acceleration due to
gravity as explained in the notes above)

C. Cancel out the unnecessary terms in part b – do it right there (there are no
initial horizontal motions) and write down the useful equation.

e. Substitute w in the coriolis equation (leftover in part c)
f.
Integrate your equation (zero to u and zero to t). You should end up with an
expression for u as a function of t.

g. But what you need is the displacement x, so you need to change u in terms of
x and integrate again (zero to x and zero to t). You should end up with an
expression for x as a function of t. This is not the end of the problem since
you don't have t. All you have is h.
