Ashopper pushes a grocery cart 20.0 m at constant speed on level ground, against a 35.0 n frictional force. he pushes in a direction 25.0° below the horizontal. (a) what is the work done on the cart by the friction? (b) what is the work done on the cart by the gravitational force? (c) what is the work done on the cart by the shopper? (d) find the force the shopper exerts, using energy considerations. (e) what is the total work done on the cart?

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
