I know it suppose to be a relatively basic question but still somehow I can't fully understand it.

Let assume that a man jumps vertically on the equator, while the Earth is of course rotating. What will happen to the value of his linear momentum in the horizontal axis?

It seems to me that if the angular momentum must be conserved, than the linear momentum must decrease, because:

J = p x r

And since r is increased due to the jump

p must decrease

Is it correct? If so how is it possible since both angular momentum and linear momentum must be conserved?

Thank you kindly.
