11. Momentum & Impulse

(I) The distance between a carbon atom (m = 12 u) and an oxygen atom (m = 16 u) in the CO molecule is 1.13 x 10⁻¹⁰ m . How far from the carbon atom is the center of mass of the molecule?

(I) The cm of an empty 1750-kg Jeep is 2.40 m behind the front of the Jeep. How far from the front of the Jeep will the cm be when two people sit in the front seat 2.80 m from the front of the Jeep, and three people sit in the back seat 3.90 m from the front? Assume that each person has a mass of 65.0 kg.

(II) A uniform thin wire is bent into a semicircle of radius R. Determine the coordinates of its center of mass with respect to an origin of coordinates at the center of the “full” circle.

(II) A 52-kg woman and a 72-kg man stand 8.6 m apart on nearly frictionless ice.

(a) How far from the woman is their cm?
