Applied Mechanics and Graphic Statics Two balls of masses 3 kg and 6 kg are moving with velocities of 4 m/sec and 1 m/sec respectively, towards each other along the line of their centers. After impact the 3 kg ball comes to rest. This can happen only if the coefficient of restitution between the balls is 1/3 2/3 1/5 3/5 1/3 2/3 1/5 3/5 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 Half the original velocity in the opposite direction Original velocity in the same direction Original velocity in the opposite direction Half the original velocity in the same direction Half the original velocity in the opposite direction Original velocity in the same direction ANSWER DOWNLOAD EXAMIANS APP
