A 44.0 kg body is moving in the direction of the positive x-axiswith a speed of 373 m/s when owing to an internal explosion, itbreaks into three pieces. One part, whose mass is 6.5kg, moves awayfrom the point of explosion with a speed of 438 m/s along thepositive y-axis. A second fragment, whose mass is 5.0 kg, movesaway from the point of explosion with a speed of 378 m/s along thenegative x-axis.
What is the speed of the third fragment? Ignore effects due togravity. Â
How much energy was released in the explosion?
