1. Homework Statement

When baseball outfielders throw the ball, they usually allow it to take one bounce, on the theory that the ball arrives at its target sooner that way. Suppose that, after the bounce, the ball rebounds at the same angle θ that it had when it was released (as in the figure below), but loses half its speed.

ETA: Hopefully this figure shows up...I attached it.

(a) Assuming the ball is always thrown with the same initial speed, at what angle θ should the ball be thrown in order to go the same distance D with one bounce (blue path) as a ball thrown upward at phi = 29.2° with no bounce (green path)?

(b) Determine the ratio of the times for the one-bounce and no-bounce throws.

2. Homework Equations

(a) I really don't know where to start.

(b) t1b/t0b

3. The Attempt at a Solution

I have no clue where to start. This is my first physics class and I'm stuck with an awful professor, and I'm lost. Help?
