N smooth spheres are placed in a row and their masses are in the ratio `1 : (1)/(e ): (1)/(e^(2)) …… (1)/(e^(N - 1))` where e = coefficient of restitution. If velocity v is given to the first sphere, find the velocity of the last sphere.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BSL_XI_RT_P12_E01_533_Q01.png" width="80%"
