The picture below represent the motion of the jet-powered car as it accelerates toward its top speed,.Time starts at zero for this motion (as if measured with a stopwatch), and the position and velocity are initially 200 m and 15 m/s, respectively. 1. From the position graph, calculate its velocity at point P and Q. 2. From the velocity graph, calculate its total displacement. 3 From the velocity graph, calculate its acceleration.

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
