Q: A plane is flying horizontal to the ground with uniform velocity Vo. A stone is thrown at it with velocity V1 and angle alpha to the horizontal. If the stone hit the plane, at what height is it flying?(adsbygoogle = window.adsbygoogle || []).push({});

The simple equations of uniform acceleration are available to me.

We obviously have to equate

x coordinate of plane during collision = x cooridinate of stone during collision

y coordinate of plane during collision = y coordinate of ston during collision.

I have attached an image of how I percieve this question. Sorry for the crappy drawing.

Anyway, my question is how to write the equations of motion for the plane and stone. Thank you.
