A 40 lb missile moves with a velocity of 150 ft/sec. It is intercepted by a laser beam which causes it to
explode into two fragments A and B which weigh 25 lb and 15 lb, respectively. If the fragments A and B
travel 45 degrees counter-clockwise from horizontal and30 degrees clockwise from horizontal,
immediately after explosion, find the magnitude of velocity of fragment A.
