Three cricket balls have masses of 4 kg, 6 kg, and 8 kg, respectively. The ball A has a velocity of 12 m/s while the other balls are initially at rest. The ball A collides with the ball B and rebounds in the opposite direction with a velocity of 7 m/s. (a) Calculate the momentum of ball A before the first collision. (b) Calculate the velocity of ball B after the first collision. Ball B now hits ball C (which has gum on it) and sticks to it. (c) What is the velocity of the balls after this second collision

if you answer my question i will answer yours

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
