A reluctant 5-year old, whose mass is 26.2 kg, is pushed at constant speed into a washroom for a bath. His father pushes him 9.53 m along a level floor with a force directed 28.1° below the horizontal. If the co-efficient of kinetic friction between the floor and the child's socks is 0.186, how much work is done by his father in pushing him into the washroom?
How much energy was lost through the frictional force?
