A heavy ball of mass 2M moving with a velocity v0 collides elastically head on with a cradle of three identical ball each of mass M as shown in figure. Determine the velocity of each ball after collision. If two balls collide in air while moving vertically then linear momentum of the system is conserved [...]

In Fig. there are n identical suspended with wires of equal length. The spheres are almost in contact with each other. Sphere 1 is pulled aside and released. If sphere 1 strikes sphere 2 with velocity u. find an expression for velocity vn of the nth sphere immediately after being struck by the one adjacent to it. The coefficient of restitution for all the impacts is e.
