A 36.0-kg body is moving in the direction of the positive x axis with a speed of 318 m/s when, owing to an internal explosion, it breaks into three pieces. One part, whose mass is 8.5 kg, moves away from the point of explosion with a speed of 359 m/s along the positive y axis. A second fragment, whose mass is 5.0 kg, moves away from the point of explosion with a speed of 370 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity. 620.17 m/s O How much energy was released in the explosion? 3.32-106 J O
