While on a ski tour across the Athabasca glacier, a team sets out toward a hut located 5.0 km away in a direction 36 north of east. After traveling in a straight line for 2.5 km, they stop and discover that they have been traveling 26 north of east, because their guide misread his compass, oops. What is the magnitude, and the direction (relative to due east) of the displacement vector now required to bring the team to the hut? Include a large, 4-page sized sketch in your solution.

Suppose a boulder breaks loose from the top of this cliff, and falls unopstructed to the ground. (a) How fast will it be going when it strikes the ground, neglecting air resistance?
