A 932 kg car is traveling around an unbanked tum with a radius of 82 m. What is the maximum speed that this car can round this curve before skidding:
a) if the coefficient of friction is 0.95?
b) if the coefficient of friction is 0.40?

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

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
