we know , v = dx/dt

a = dv/dt

x = a_o + a₁t + a₂t²

v= dx/dt = 0 + a₁ + 2a₂t

a=dv/dt = d/dt (a₁+2a₂t)

=0+2a₂

differntiation of constant is 0...

so accleration of particle = 2a₂

option c is correct

x=a₀+a₁t +a₂t²

accn=d²x/dt²=a₂

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.
