Applied Mechanics and Graphic Statics A ball of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/sec hits an identical stationary ball ‘B’ on the table. If the impact is perfectly plastic, the velocity of the ball ‘B’ just after impact would be 10 m/sec 5 m/sec Zero None of these 10 m/sec 5 m/sec Zero None of these ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A rod 5 m in length is moving in a vertical plane. When it is inclined at 60° to horizontal, its lower end is moving horizontally at 3 m/sec and upper end is moving in vertical direction. The velocity of its upper end, is 0.5 m/sec 1.5 m/sec 2.5 m/sec 1.0 m/sec 0.5 m/sec 1.5 m/sec 2.5 m/sec 1.0 m/sec ANSWER DOWNLOAD EXAMIANS APP
