Sir,

an insect of mass 'm' is initially at rest at one end of a stick of length 'L' and mass 'M' , which rests on a smooth horizontal floor.The cofficient of friction between the insect and stick is 'k'. The insect starts moving to reach the other end in shortest possible time.

Q1.Find the time taken to reach the other end?

Q2.What is the magnitude of linear momntum of insect at time t?

Q3.What is the maximum speed aquired by the stick??

please sir while answering do explain ur approach..!!

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.
