A small particle of mass m attached with a light inextensible thread of length L is moving in vertical circle.Minimum velocity requried for the particle to go around complete vertical circle is √gL.In the given case particle is moving in a complete vertical circle and ratio of its maximum to minimum velocity is 2:1.Find the minimum velocity of particle_______________________

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.
