If the acceleration of a particle is the function of distance as a = f(x). Then :- a) the velocity must be function of displacement. b) the velocity versus displacement graph cannot be a straight line. c) the velocity may be the function of displacement d) the acceleration displacement graph may be straight line. Please Give Solution

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.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
