Hi,

I have already answered this question. pls check your Account profile.

However,

the answer is:

For nth second eqn. of displacement is:

S = u + (a/2)*(2n-1)

from rest u = 0.

S = (a/2)*(2n-1)......................(1) in last n second.

acccelration after 2n second,

a = v/2n.............(2)

put (2) eqn. in eqn. (1) we get,

S = (v/2n) (2n-1) meter

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.
