Question

Consider two people

pushing a toboggan with four children on it up a snowcovered slope. Construct a problem in which you calculate

the acceleration of the toboggan and its load. Include a freebody diagram of the appropriate system of interest as the

basis for your analysis. Show vector forces and their

components and explain the choice of coordinates. Among

the things to be considered are the forces exerted by those

pushing, the angle of the slope, and the masses of the

toboggan and children.
