d10 ocean Starting from rest, a penguin weighing 4kg, slides down a snowy incline at 66.8° to horizontal. The incline is 21.75m long (d 1 in diagram). Then the penguin slides along a long snow-covered horizontal section of length 18.8m (d2 in diagram), then off of a 33.18m tall cliff (h in diagram) into the ocean. The coefficient of friction between the penguin and all snowy surfaces is 0.266. Ignoring air drag, what is the penguin's speed when reaching the water surface? Include SI units. Report your answer to 3 significant digits.
