A bomb explodes into three identical pieces. One flies in the + y-direction at 17.3 m/s, a second in the - x-direction at 11.6 m/s.

What's the magnitude of the velocity of the third piece?

What's the direction of the velocity of the third piece? Count counterclockwise from the + x axis.

From the conservation of energy Summation of momentum i.e mass x velocity will be zero. In the instant case we have :
m |dw:1352764568743:dw|
