James stewart, 2002 motorcross/supercross rookie of the year, is leading a race when he runs out of gas near the finish line. he is moving at 16 m/s when he enters a section of the course covered with sand where the effective coefficient of friction is 0.90. will he be able to coast through this 15-m-long section to the finish line at the end? if yes, what is his speed at the finish line?

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
