two blocks tied to a massless string of length 3m are placed on a rotating table on opposite ends. the blocks are of mass 1kg and 2kg. the axis of rotation is 1m from 1kg mass and 2m from 2kg mass. the angular speed is 4 rad/s. ground below 2 kg block is smooth and below 1 kg block is rough. find tension in the string, force of friction on 1 kg block and its direction

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.
