Question

A ball is thrown vertically upward with an initial speed of 20 m/s. Two seconds later, a stone is thrown vertically (from the same initial height as the ball) with an initial speed of 24 m/s. At what height above the release point will the ball and stone pass each other?

Answer 1

This question belongs in Physics.

And you should try and work through your other problem there because the equations you need to answer that question are exactly the same ones you'll need for this question.

Answer 2

Mk, thanks
