Applied Mechanics and Graphic Statics A ball moving with a velocity of 5 m/sec impinges a fixed plane at an angle of 45° and its direction after impact is equally inclined to the line of impact. If the coefficient of restitution is 0.5, the velocity of the ball after impact will be 2.5 m/sec 1.5 m/sec 3.5 m/sec 0.5 m/sec 2.5 m/sec 1.5 m/sec 3.5 m/sec 0.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
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
