Type 1 to 2 paragraphs describing the changes in potential, kinetic, and thermal energy of the cart at each of the four positions along the track. Be sure to define your system. Also include the positions of the cart where are each form of energy is at its maximum and minimum values.

Determine the maximum r-value of the polar equation r =3+3 cos 0

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

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
