Consider a 10kg mass located at (0,0)-the origin-and a 5kg mass located at (20,0). (Be careful to locate these points in there proper place on the cooridinate system! Distance are in meters.)
What would be the magnitude of the gravitational force between these two points?
What would be the net force placed on a 2C charge placed at (15,0) meters?
A weight lifter lifts a 420 N set of weights from ground level to a position over his head, a vertical distance of 1.70 m. How much work does the weight lifter do, assuming he moves the weights at constant speed?
