A particle of mass 1 kg is given a horizontal velocity of 4 m/s along a horizontal surface, with which it has a coefficient of friction (both static and kinetic) of 0.4. The particle strikes a fixed ideal spring of force constant 6 N/m after travelling a distance of 0.25 m. Assume acceleration due to gravity is 10 m/s2. Find the final displacement of the particle from its starting point.{i am asking the position of the point second time where it finally ends up and no further motion takes place}ans is 7/12
