A baseball is struck by a batter and is caught by a fielder 100 m away 5.00 s.

A. At what horizontal velocity does the ball travel on its way to the fielder?
- I found this out to be 20.0 m/s
B. How long after being hit does the ball reach max height?
C. Determine initial velocity of the ball when first hit.
D. What is max height ball reaches in its flight?
E. What is the magnitude of the total initial velocity of the ball when hit?
F. At what angle to the horizontal does the ball leave the bat?

Just need someone to guide me through this. Multi-part question so you don;t have to do it all. you can just tell me how i would figure out each part and I would appreciate it.

Thanks
 
Sorry Chris, there is enough info.

Assumuing there is no air resistance, you know that the ball was falling under gravity for half of its flight, so 2.5 seconds
s= 1/2 * 9.8 * 2.5^2, where s = the maximum height of the ball.

Once you know how far it fell, you can find how fast it was falling when it was caught. You can assume that that was the vertical speed when it was hit - and you have already found the horizontal speed. And from having the two components, you can easily find the angle.

Plug and chug.

OK?
