A 60.0 kg trunk starts at rest on a student's dorm room floor. The student pushes the trunk a distance of 10.0 m along a straight line. The student accomplishes this by exerting on the trunk a constant force of 300 N, directed 20 degrees below the horizontal. The coefficient of kinetic friction between the trunk and the floor is 0.250 . In the following, consider the period of time during which the student pushes the trunk along the 10.0 m distance. For simplicity, assume that g = 9.80 m/2. 300 N
