Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 50 m/sec 40 m/sec 20 m/sec 30 m/sec 50 m/sec 40 m/sec 20 m/sec 30 m/sec ANSWER DOWNLOAD EXAMIANS APP
