Masses of 1.0 kg, 2.0 kg, and 3.0 kg are each separately subject to a net force in the positive x direction of 22 N. What is the acceleration of the center of mass of the system? I did 22N/ 1+2+3 = 3.67 m/s^2 but it is saying its wrong. Am I missing something?
Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.3 kg at (0.0, 3.7) m, and 4.0 kg at (3.5, 0.0) m. Where should a fourth object of 7.9 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?
Consider the following mass distribution where the x-and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.2 kg at (0.0, 4.7) m, and 4.0 kg at (3.2, 0.0) m.Where should a fourth object of 7.3 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?
Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.6 kg at (0.0, 3.4) m, and 4.0 kg at (2.6, 0.0) m. Where should a fourth object of 7.4 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m? x = m y = m
the mass and coordinates of three objects are given below: m1 = 6.0 kg at (0.0, 0.0) m, m2 = 1.3 kg at (0.0, 4.2) m, and m3 = 4.0 kg at (3.1, 0.0) m. determine where we should place a fourth object with a mass m4 = 7.5 kg so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m.
Three masses are in a configuration as follows: M1 = 1.0 kg at coordinate ( 0, 0) M2 = 2.0 kg at coordinate ( 3.0 m, 0) M3 = 2.0 kg at coordinate ( 0, 4.0 m) What is the total gravitational potential energy of the system?
6. Spinning Dumbbell Two small masses (m = 3.0 kg; M = 5.0 kg) are attached to the ends of a thin light rod that isL = 16.0 cm long. The dumbbell is placed vertically at the edge of a frictionless table as shown in the diagram. The rod is struck at a height of ? = 12.0 cm above the center of mass of the lower mass, m, with an impulsive blow that lasts½ millisecond, and that rises linearly...
