Just differentiate the given equation twice w.r.t t and you will get the acceleration now multiply it with mass you will get the answer.

We know
s=ut+1/2gt^2
Now,
ds/dt=v=u+gt
also,
dv/dt=a=g
Force=mass×acceleration
Hence the required answer is
Force=mass×g

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.
