Two blocks, with masses m₁ =4.6 kg and m₂ =≅ 3.8 kg, are connected by a light spring on a horizontal frictionless table. At a certain instant, when m2 has an acceleration a₂ = 2.6 m/s², (a) what is the force on m₂ and (b) what is the acceleration of m₁ ?

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.
