An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is 2.40 x10-28 kg, and that of the heavier fragment is 1.64 x10-27 kg. If the lighter fragment has a speed of 0.893c after the breakup, what is the speed of the heavier fragment?
Thank you very much for any help you can give me on this question! I really appreciate it!

I'm 16 yrs old, and 5'6. I weigh about 145lbs. To me, that sounds huge, but I do workout rather often, and I've heard muscle weighs more than fat. I also eat rather healthy, but I probably do eat a little too much every couple of days. So am I fat??

Are your judegements biased based on your preference for that song? For example, If its a song you like do you think "rock on" but if its a song you hate you think "what a distraction." Or do you always think its rude and unacceptable to blast music.

If your answer is no, how come so many supposed Muslims are killing for the sake of Islam? Do I have it all wrong?

I'm simply trying to understand, not provoke or offend.

The Ottawa treaty was signed to ban the use and stockpiling of anti-personnel (AP)mines. Most of the world considers APs illegal, yet noone denounces Iraqi "insurgents" for using them.
Technically, IEDs are AP mines. More than 10,000 est. Iraqi civilians have been decimated by these landmines.
