2. A grenade of mass 3.60 kg is at rest on a smooth, frictionless surface when it suddenl explodes into three pieces. A 1.50 kg pieces flies off horizontally at 300 m/s [South], and a 0.90 kg piece flies off horizontally at 400 m/s [E 30° N]. Calculate the mass an velocity of the third piece. (m3 = 1.2 kg; v3f = 344 m/s [W41S])

2. A grenade of mass 3.60 kg is at rest on a smooth, frictionless surface when it suddenly
explodes into three pieces. A 1.50 kg pieces flies off horizontally at 300 m/s [South],
and a 0.90 kg piece flies off horizontally at 400 m/s [E 30° N]. Calculate the mass and
velocity of the third piece. (m3 = 1.2 kg; v3f = 344 m/s [W41S])
