Asked by Kellie

A 3.0kg object originally at rest explodes and splits into three fragments. One fragment has a mass of .50kg and flies off along the negative x-axis at a speed of 2.8m/s, and another has a mass of 1.3kg and flies off along the negative y-axis at a speed of 1.5m/s. What are the speed and direction of the third fragment?
