A 10kg mass is moving to the right with a velocity of 15 m/s. A 13kg mass is moving to the left with a velocity of 6.0 m/s. Assuming that these two
masses have a head on collision and stick together, what would be the
final velocity and to what direction? *

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
