A) (6 points) Assuming that the sled starts from rest, what is the sled's energy at the top of the hill? ) (7 points) The students first prediction models the snow as being frictionless. If the snow is treated as being frictionless, what is the sled's speed at the bottom of the hill? (6 points) The students now refine their prediction and model the snow as having a frictional force of 206 N. What is the work done by the frictional force as the sled goes from the top of the hill to the bottom of the hill? (6 points) Including this 206 N frictional force from the snow, what speed will the sled now have at the bottom of the hill? (1 point) Does the sled have a larger speed when the snow is treated frictionless or frictional surface
