Consider the following mass distribution where the x- and y-coordinates are given in meters:0 kg at (0.00) m, 2.5 kg at (0.8) m, and 4.0 kg at (2....

Consider the following mass distribution where the x- and y-coordinates are given in meters:5.0 kg at (0.0.0.00) m, 2.5 kg at (0.0,3.8) m, and 4.0 kg at (2.8,0.0) m. Where should a fourth object of 7.8 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0,0.0) m? (x,y)?

An object is acted on by a single nonzero force of magnitude F. Is it possible for the object to have zero angular acceleration? a. Yes or b. No


A car mass 1000 kg moves with a speed of 50 m/s on a circular track of radius 100 m. What is the magnitude of its angular momentum (in kg.meters per second squared) relative to the center of the race track? a. 5.0*10^2 b. 5.0*10^6 c. 2.5 *10^4 d. 2.5*10^6
