Six forces lying in a plane and forming angles of 60degrees relative to one another are applied to the centre of a homogenous sphere with a mass m=6kg.These forces are radially outward and consecutively 1N,2N,3N,4N,5N and 6N.The acceleration of the sphere is -----------.

Explain the procedure to find out acceleration.

(Answer is 1m/s^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.

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.
