The final velocity of the particle for the first t seconds is given as v 1 =at, for the next t seconds is, v 2 = a t + a t / 2 and so on. So yes, you can apply the infinite geometric sum for these.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
