PROBLEM SET 4:Due next Weds. 09/30/09 before classProblems: 7.40, 8.41, 8.60, and the following:Consider an object of massm= 1 kg attached to a spring of spring constantk= 1N/m as shown. The object slides with a coefficient of kinetic frictionμK= 0.1 and acoefficient of static frictionμS= 0.2.Sketch its motion (plotxvs.t) when the object is displaced by an amountAfromthe spring’s equilibrium and released for the following cases:a)A= 1 meterb)A= 3 metersc)A= 5 metersIn each case (i.e., for a, b, and c) you must findallthe locations at which theobject stops. This will include the occasions at which it changes direction and then
