An object is moving forward along a straight line. The distance the object travels (in meters) from its starting position t seconds after it started moving is given by �(�) = 3√�. Determine the average velocity of the object over the interval from t=1 to t=4.

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
