An incompressible fluid flows through a horizontal pipe. At one point in the pipe the pressure in the fluid is p1 and the fluid speed is v1. further down the pipe the pressure is p2 and the speed is 2v1. what can be concluded about p1 and p2?

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.
