Well, this is my first of most likely many posts. Here goes the homework problem:(adsbygoogle = window.adsbygoogle || []).push({});

An Engineering student wants to throw a ball out of a third story window (10 m off the ground) onto a target on the ground placed 8.0m away from the building. (a) If the student throws the ball horizontally, with what velocity must the ball be throw? (b) What must the velocity of the ball be if it's thrown up at an elevation angle of 29degrees? (c) What is the ball's time of flight in case of (b)?

I understand how to do both parts (b) & (c) but part (a) is giving me a bit of trouble.

The only way that I've figured out how to do part (a) is to make a parabola out of the figure then figure out the horizontal component at the max height (of 10m). This seems to be a roundabout way of completing the problem.

So, if anyone has a suggestion please share.

Thank You
