A block of mass 0.18 kg is attached to a spring of force constant 2 N/m. The coefficient of friction between the block and the floor is 0.1. Initially the block is at rest and the spring is unstretched.

The work done on a particle of mass m by a force k ( x / (x^2 + y^2)^3/2 i + y / ( x^2 + y ^2 )^3/2 j ) ( K being the constant of appropriate dimensions when the particle is taken from
