A 149-N box sits in a wagon at rest on horizontal ground. A child walks up and pulls horizontally on the wagon, giving it an acceleration of 9.5 m/s². Calculate the resulting magnitude f of the friction force acting on the box if μg 0.82 and μk =0.37 between the box and the wagon. [Hint: As part of your solution, check to see if the box experiences static or kinetic friction.] f = __________ N
