(a)Calculate the work done by moving a 50 kg mass along each of the legs of the path shown below. What is the total work expended when going along the entire path? Show all work. Don't just state any obvious results, if any.
AB= 5m
BC= 10m
CD= 19.14m
DA= 10m
Angle between AB= 45 degrees,
angle between b and c equals 45 degrees.
(b) Do part a when the path ABCD lies on a level floor with coefficient of kinetic friction µk= 0.15 Show all work.
