Applied Mechanics and Graphic Statics Newton’s Law of Motion is: To every action, there is always an equal and opposite reaction The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force All listed here To every action, there is always an equal and opposite reaction The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force All listed here 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 Original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the same direction Half the original velocity in the opposite direction Original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the same direction Half the original velocity in the opposite direction ANSWER DOWNLOAD EXAMIANS APP
