A 5.0 kg object is initially at rest and then moves on africtionless horizontal surface. A force in the +x direction with amagnitudeF(x) = (5.0 N/m)X - 3.0 N is applied to the object. At whatposition will the object have a speed of 20.0 m/s if it was at theorigin atthe beginning of the motion. (10 points). You will not receivecredit for this problem if you use concepts from chapter 7(conservation of mechanical energy) to solve this problem.
