A particle of mass m is subjected to a net force (t) given by (t) that is, F(t) equals Fo at t = 0 and decreases linearly to zero in time T. The particle passes the origin x = 0 with velocity . Show that at the instant t = T that F(t) vanishes, the speed v and distance x traveled are given by v(T) and x(T) , where is the initial acceleration. Compare these results with Eqs. 2-26 and 2-28.

Therefore the force experienced by the particle at t = T is zero .

Therefore, the velocity matches the magnitude of velocity calculated above.

Therefore, the position matches the magnitude of position calculated above

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.
