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 same direction Original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the opposite direction Original velocity in the same direction Half the original velocity in the opposite direction ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The displacement of a particle which moves along a straight line is given by S = 4t³ + 3t²- 10 where ‘S’ is in meters and t is in seconds.
