ok so I really don't get 2d collisions and I thought I knew how to do this one but I have no idea:
A 104 kg baseball player jumps up verticlly to catch a baseball of mass .254 kg traveling horizontally with a speed of 28.6 m/s. If the vertical speed of the player is .258 m/s the instant he catches the ball, detemine him speed just after the catch.
please help or let me know how on Earth I would solve this!

bobpursley,
You have the initial vertical speed, the horizontal speed will be given by the law of conservation of momentum.
In the horizontal...
massball*speedball=(massball+massplayer)Vfh
solve for the Vfh (final horizontal speed of the ball in the glove)
Now add vectors horizontal speed of the player and vertical speed of the player.

Ty,
Hi I know this is a few days later and I am not sure if you will see it but when I tried this problem I got it wrong/
I got .3276798204 m/s and it's incorrect. If you see this please help!
