Let I be the MI of a uniform square plate about an axis AB that passes through the centre of the plate and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the centre of the plate and makes an angle "a" with AB. The MI of the plate about the axis CD is then?

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.
