According to Newton's third law of motion, forces always occur in pairs called action-reaction pairs. Which of the following statements is/are FALSE about these forces? 1 If the action is a non-contact force, the reaction can be a contact force or a non-contact force. 2 The action force is equal to the reaction force. 3 The action and reaction forces cannot act on the same body.

(b) Find the magnitude and direction of the net force. (c) If Andrea and Jennifer’s housemates, David and Stephanie, disagree with the move and want to prevent its relocation, with what combined forceFDS should they push so that the couch does not move?
On June 25, 1983, shot-putter Udo Beyer of East Germany threw the 7.26-kg shot 22.22 m, which at that time was a world record. (a) If the shot was released at a height of 2.20 m with a projection angle of 45.00, what was its initial velocity? (b) If while in Beyer’s hand the shot was accelerated uniformly over a distance of 1.20 m, what was the net force on it?
A moving object is acted on by a net force. Give an example of a situation in which the object moves (a) in the same directionas the net force, (b) at right angles to the net force, or in theopposite direction of the net force. Draw and Explain
A small car collides with a large truck. (a) Isthe magnitude of the force experienced by the car greater than, lessthan, or equal to the magnitude of the force experienced by thetruck? (b) Choose the best explanation from among the following:I. Action-reaction forces always have equal magnitude.II. The truck has more mass, and hence the force exerted on itis greater.III. The massive truck exerts a greater force on the lightweight car.
