Question 1: Three particles are placed in the xy plane. A 69 g particle is located at (-8.0, 7.0) m, and a 67 g particle is positioned at (-6.0, -5.0) m. Where must a 27g particle be placed so that the center of mass of this three particle system is located at the origin? Your Answer: (35, -5.5) Question 2: A 50.0 kg painter climbs up a 6.00 m ladder of negligible weight which is leaning 52.0 ° on a wall. The coeficient of fraction on the wall and ground are both μ=0.200. What is the maximum distance the painter can move up the ladder without it falling? Your Answer: 1.71 m
