A 32.0-kg body is moving in the direction of the positive x axis with a speed of 382 m/s when, owing to an internal explosion, it breaks into three pieces. One part, whose mass is 7.5 kg, moves away from the point of explosion with a speed of 355 m/s along the positive y axis. A second fragment, whose mass is 3.0 kg, moves away from the point of explosion with a speed of 438 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity. Submit Answer Tries 0/8 How much energy was released in the explosion? Submit Answer Tries 0/8
