Can someone help me understand where to at least start with this EC assignment? What 2 problems could I write?

LIGHTHOUse A particle starts at rest and moves with velocity PILE LADER along a 10-foot ladder, which leans againsta trough with a triangular cross-section two feet x. GATHERING PEBBLES ON THE BEACH wide and one foot high. Sand is flowing out of the trough at a constant rate of two cubic feet per hour, forming a conical pile in the middle of a sandbox which has been formed by cutting a square of side x from each corner of an 8" by 15" piece of cardboard and folding up the sides. An observer watches the particle from a lighthouse one mile off shore, peering through a window shaped like a rectangle surmounted by a semicircle Extra-Credit Assignment: Write and solve at least two calculus" problems based on the information given above *A calculus problem is a problem that requires either differentiation or integration to solve it accurately
