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 None of these 10 m/sec Zero 5 m/sec None of these 10 m/sec Zero 5 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The following is not a law of static friction: The force of friction depends upon the roughness of the surface The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction depends upon the roughness of the surface The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move ANSWER DOWNLOAD EXAMIANS APP
