A 78g particle moving with an initial speed of 39m/s in the positive x direction strikes and sticks to a 160g particle moving with 33m/s in the positive y direction.

How much kinetic energy is lost in this collision? Answer in units of J.


Can someone please tell me how to solve this problem. Or at least set me up with the equations.


Thanks.

Read that, it should help you out.

wow man that's an awesome resource. i love anything that uses plain english.

have any links to the same person talking about power/force/energy/friction?

seeing as i tried that equation and apparently i still have the wrong answer...anyway i can get a step by step? i must be missing something?
