A bike traveling initially at a speed of 32 m/s accelerates uniformly at the rate of 3 m/s2 for a distance of 40 meters. The
bike's velocity after covering this distance is m/s.

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 1.90
