"Explosion" (q34)

I have not sure how to get started with this question:

Hope that anybody can help.
 
Physics news on Phys.org
What conservation law applies in the case of an explosion?
 
I see, followed is the working:

let direction of one of the particles with 20m/s as x direction
in x direction
0=2*20+2*20*cos60+2Vx
in y direction
0= 0 +2*20*sin60+2Vy
V=sqrt(Vx^2+Vy^2)=34

ke=0.5*2*(20^2+20^2+34^2)=2.0KJ, answer is c.
 
Is it correct?
 
I agree with your answer.
 
I see, thanks for the confirmation :)
