Applied Mechanics and Graphic Statics A bullet weighing 200 g is fired horizontally with a velocity of 25 m/sec from a gun carried on a carriage which together with the gun weighs 100 kg. The velocity of recoil of the gun, will be 1.00 m/sec 0.05 m/sec 1.5 m/see 0.01 m/sec 1.00 m/sec 0.05 m/sec 1.5 m/see 0.01 m/sec ANSWER DOWNLOAD EXAMIANS APP
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 0.5 m/sec 1.5 m/sec 3.5 m/sec 2.5 m/sec 0.5 m/sec 1.5 m/sec 3.5 m/sec 2.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
