The work W done on an object by a constant force is defined as W = F. d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.
Answer:
A, B, D.
Explanation:
If Jamy pushes on Anita, then by Newton's 3rd Law there will be a reaction force equal in magnitude and opposite in direction. This means that A and D are correct, while C, E, F and G are incorrect. Since the magnitude of any of these forces can be calculated with Newton's 2nd Law, F=ma for either Jamy or Anita, this means that B is correct.
