Question 1 A system consisting of two objects has a total momentum of (18 kgm/sec)i and its center of mass has the velocity of (3 m/s)i.One of the object has the mass 4 kg and velocity (1.5 m/s)i.The mass and velocity of the other objects are (a) 2 kg, (6 m/s)i (b) 2 kg, (-6 m/s)i (c) 2 kg, (3 m/s)i (d) 2 kg, (-3 m/s)i
Common center of mass problems involve composite objects made of simple uniform objects attached together, such as rods, disks, shells, and other basic shapes. The solutions to these problems use the formulas for the center of mass of basic uniform objects and the principle of superposition.
Two point masses 3 kg and 5 kg are at 4 m and 8 m from the origin on X-axis. Locate the position of center of mass of the two point masses (i) from the origin and (ii) from 3 kg mass. Solution. Let us take, m1 = 3 kg and m2= 5 kg. (i) To find center of mass from the origin:
