Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 71 N/m, attached to a 11-kg block in an incline (8= 21°). With the spring initially at equilibrium position, the block was pulled 0.4 meters down the incline by a 28-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.3, determine the work done by the spring (in Joules). Use g = 9.81 m/s² www

Consider a block of mass 0.200 kg attached to a spring of spring constant 100 N/m.

A mysterious force acts on all particles along a particular line and always points towards a particular point P on the line. The magnitude of the force on a particle increases as the cube of the distance from that point; that is Fr3 , if the distance from P to the position of the particle is r. Let b be the proportionality constant, and write the magnitude of the force as F=br3. Find the potential energy of a particle subjected to this force when the particle is at a distance D from P, assuming the potential energy to be zero when the particle is at P.

Repeat the preceding problem, but this time, suppose that the work done by air resistance cannot be ignored. Let the work done by the air resistance when the skier goes from A to B along the given hilly path be —2000 J. The work done by air resistance is negative since the air resistance acts in the opposite direction to the displacement. Supposing the mass of the skier is 50 kg, what is the speed of the skier at point B ?
