Center of Mass 1} Three objects are located in a coordinate system as shown in Figure a. a) Find the center of mass. b) How does the answer change if the ehject on the left is displaced upward by 1.00 In and the object on the right is displaced downward by [3.500 m Fig.h'? Treat the objects as paint particles. 5.00 kg 2) If 1.00 kg is added to the masses on the left and right in Figure. :1, does the center of mass A. Move to the left B. Move to the right C. Remain in the same position 3) If a fourth particle of mass 2.00 kg is placed at (0, 0.25m) in Figure :1, find the x and v- coordinates of the center of mass for this system of four particles. 4} Consider the following mass distribution, where x and ycoordinstes are given in meters: 5.00 kg at (0.0, 0.0)111, 3.0 kg at {0.0, 4.0] in, and 4.0 kg at {3.0, 0.0} no. Where should a fourth object of 3.0 kg he placed so that the center of mass of the four-object arrangement will he at (0.0, 0.0) m? Question 3 A 50.0 N (1 1-11:) bowling ball is held in a person's hand with the forearm horizontal, as in Figure. The biceps muscle is attached (10300 In fromthe joint, and the hall is 0.350 m from the joint. Find the upward force F exerted by the biceps on the forearm (the ulna) and the downward force R exerted by the humerus on the forearm, acting at the joint. Neglect the weight of the forearm and slight deviation from the vertical of the biceps
