given v proportional to x

so, v=kx where v=dx/dt

dx/dt = kx

on integrating both sides ,we have

ln x = kt + c

here k,c are unknowns

at t=0 , x=2

t=10 , x=4

t=5 , x = ??

from above

ln 2 = c .......(1)

ln 4 = 10k + c .....(2)

ln x = 5k + c ....(3)

on solving gives , x=8^1/2

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.
