Let m1=1kg,m2=2kg and m3= 3kg. Find the accelerations of m1, m2 and m3. The string from the upper pulley to m1 is 20cm when the system is released from rest. How long will it take before m1 strikes the pulley? HC Verma part1 page number 81 and question number 28

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.
