As George says, you really have to work at it to make a prop stop. It will
windmill at glide speed, and the magnetos will spark their little hearts out
during every revolution until the fuel-air mixture returns to the cylinders.

If you do stop the prop...on purpose, by sticking the nose way up in the
air...you will have to dive to about 120 to get it rotating again.

I was just wondering if best glidespeed in say a cessna 152 will be fast
enough to
get the engine started if you encountered a battery failure or starter
failure.
