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 Zero 10 m/sec 5 m/sec None of these Zero 10 m/sec 5 m/sec None of these ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A particle moves along a straight line such that distance ‘x’ traversed in ‘t’ seconds is given by x = t²(t + 1), the acceleration of the particle, will be 6t + 2 6t - 2 3t³ - 2t 3t² + 2t 6t + 2 6t - 2 3t³ - 2t 3t² + 2t ANSWER DOWNLOAD EXAMIANS APP
