Concept

Problem: A 12-pack of Omni-Cola (mass 4.30 kg) is initially at rest on a horizontal floor. It is then pushed in a straight line for 1.20 m by a trained dog who exerts a horizontal force with magnitude 36.0 N. You may want to review (Pages 177 - 182). For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Using work and energy to calculate speed.Use the work-energy theorem to find the final speed of the 12-pack if there is no friction between the 12-pack and the floor.Use the work-energy theorem to find the final speed of the 12-pack if the coefficient of kinetic friction between the 12-pack and the floor is 0.30.
