A shell of mass 0.4 kg is at rest in a gravity-free environment when it suddenly explodes into three fragments. The mass and x,y components of two of the fragments is given in the table:


particle mass (kg) vx (m/s) vy (m/s)

[1] 0.12 25 58

[2] 0.04 -7.5 13

[3] ? ? ?



particle 1 : .12 [mass] ; 25 [vx (m/s)] ; 58 [vy (m/s)]
particle 2 : .04 [mass] ; -7.5 [vx (m/s)] ; 13 [vy (m/s)]
particle 3 : ? [mass] ; ? [vx (m/s)] ; ? [vy (m/s)]


Find the mass and x,y components of the velocity of the third fragment.
