Arace car completes the final lap of a race on a 2-kilometer circular track. at the start of the lap, it crosses the line at 60 meters/second. it completes the lap 28.57 seconds later, crossing the line at 85 meters/second. calculate the displacement and average acceleration of the car within the span of 12 seconds.

a. displacement is 0 meters, and acceleration is 0.88 meters/second^2.
b. displacement is 2,000 meters, and acceleration is 1.14 meters/second^2.
c. displacement is 0 meters, and acceleration is 70.0 meters/second^2.
d. displacement is 2,000 meters, and acceleration is 80.0 meters/second^2.
e. displacement is 0 meters, and acceleration is 0.70 meters/second^2.

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
