A block of mass m rests on a rough horizontal plane having coefficient of kinetic friction mu_(k) and coefficient of static friction mu_(s) . The spring is in its natural, when a constant force of magnitude P=(5mu_(k)mg)/(4) starts acting on the block. The spring force F is a function of extension x as F=kx^(2).( Where k is spring constant ) (a) Comment on the relation between mu_(s) and mu_(k) for the motion to start. (b) Find the maximum extension in the spring ( Assume the force P is sufficient make the block move ) .

A small coin of mass 40 g is placed on the horizontal surface of a rotating disc. The disc starts from rest and is given a constant angular acceleration alpha="2 rad s"^(-2) . The coefficient of static friction between the coin and the disc is mu_(s)=3//4 and the coefficient of kinetic friction is mu_(k)=0.5. The coin is placed at a distance r=1m from the centre of the disc. The magnitude of hte resultant force on the coin exerted by the disc just before it starts slipping on the disc is :

Coefficient of kinetic friction and coefficient of static friction between two blocks is mu_(k) and mu_(s) respectively. In general
