Question

An object with mass 2 kg is moving in the x-y plane. Suddenly the object exploded into 3 pieces. The first chip with a mass of 0.4 kg is moving at the velocity v1 = 2i + 3j. The second chip with a mass of 0.9 kg is moving at the velocity v2 = 4i - 2j. The third chip with a mass of 0.7 kg is moving at the velocity v3 = -5i - 4j. Determine the velocity vector of the object before it explodes. (hint: use the law of conservation of momentum P Start = End, where P = mv)
