A Block of mass 2kg is kept on a horizontal smooth table.It is tied to another hanging block of same mass .Moment of inertia of pulley is equal to 2kgm²,radius 1m.Assuming no slipping on the pulley ,acceleration of any of the block is(g=10)

Ans-10/3

(Please sir solve this question .Its a humble request .I am in great need for this question.)

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.
