A 50.0 kg body is moving in the direction of the positive x axis with a speed of 384 m/s when, owing to an internal explosion, it breaks into three pieces. One part, whose mass is 9.0 kg, moves away from the point of explosion with a speed of 353 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 313 m/s along the negative x axis.
What is the speed of the third fragment? Ignore effects due to gravity.
How much energy was released in the explosion?
