So...In Central Oregon there is a winter time problem that is troublesome to gardeners having to do with large masses of snow sliding off the roof and crushing plants and shrubs on the ground. Physics (in particular 2-D Kinematics) allows us to determine some features of the vegetative danger zone. We'll assume for the purposes of this activity that the roof is a typical 4 in 12 pitch (meaning it rises 40 cm and it goes inwards 120 cm ) and experiments have shown that when large amounts of snow slide off they leave the edge of the roof at 2.4 m/s. The edge of the roof is 3.3 m above the ground and 40 cm outward from the wall of the house.

I honelsty don't even know where to begin. Our teacher likes to gives us scenerios and for us to figure out possible questions that he might ask depending on the scenerio. If someone could give me a jumping off point or anything would be helpful. attached is the scenerio in picture form.
