A ball is thrown upward at an angle 30 degrees above the horizontal and lands on the top edge of a building 20 m away. The top edge is 5m above the throwing point. How fast was the ball thrown?(adsbygoogle = window.adsbygoogle || []).push({});

ANS 20 m/s.

I just can't seem to get this. It looks like there is a piece of info missing but I know that's not the case. Any hints?
