A tube 1 cm square in cross section is attached to the top of a vessel 1cm high and of cross section 100 cm square . Water is poured in the system filling it to a depth of 100 cm above the bottom of the vessel as shown in the figure find the force exerted by water against the bottom of the vessel and the weight of water in the system

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.
