Three steel spheres of equal mass are suspended from the ceiling by strings of the same length that are spaced at a distance slightly larger than the diameter of the spheres. After pulling it and Releasing it, sphere A hits sphere B, which then hits sphere C. If the coefficient of restitution between the spheres is denoted by e and by v0 the velocity of A just before it hits B, determine, (a) the velocities of A and B immediately after the first collision, b) the velocities of B and C immediately after the second crash. c) If now it is assumed that n spheres are suspended from the ceiling and that the first is pulled and released as described above, determine the velocity of the last sphere after takes the first hit. d.Use the result of part c to find the velocity of the last sphere. when n = 6 and e = 0.95.
