Hey

If we have a spring block system executing shm under normal conditions there is two block of both have mass m placed one above other have some value of friction between them if spring is attached to upper block

Then what will be maximum value of force at extremum position so that there is no relative motion between the blocks

Assume friction between earth's surface and block is zero

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.
