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 5 m/sec None of these 10 m/sec Zero 5 m/sec None of these 10 m/sec Zero ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact. If the coefficient of restitution is ½, the velocities of separation of the balls will be equal to Half the original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the same direction Original velocity in the opposite direction Half the original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the same direction Original velocity in the opposite direction ANSWER DOWNLOAD EXAMIANS APP
