A force F=Kt ( where t is the time in seconds and K=2(root2) N/s) is applied on 2kg block at t=0 as shown in figure. The displacement of 8kg block till the time when 2kg block starts slipping on 8kg block will be (coefficient of friction b/w 2kg block and 8kb block is 0.2 and b/w 8kg block and surface is zero, g=10m/s) is n/15m.Find n?

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.
