Homework Help: Physics

Posted by CONFUSED!!!! on Tuesday, October 2, 2007 at 8:34pm.

When baseball outfielders throw the ball, they usually allow it to take one bounce on the theory that the ball arrives sooner this way. Suppose that after the bounce the ball rebounds at the same angle theta as it had when released, but loses half its speed.

Assuming the ball is alyways thrown with the same initial speed, at what angle should the ball be thrown in order to go the same distance D with one bounce (lower path) as one thrown upward at angle 47.8 with no bounce (upper path?)

the only hint my teacher gave me was: solve this problem symbolically before you plug in numbers.

i don't even know where to start.
