A block of ice starts from rest on an apartment building's roof, which slopes at 41° below the horizontal. The block slides down the icy frictionless roof for 5.0 m and then leaves the edge, which is 12 m above the ground.
a. How far from the building does the block strike the ground?
b. If a 1.8 m fence stands 6.0 m from the building, show whether or not the ice block will hit the fence.
