1- If you push a 20 N horizontal force on a 2 kg mass resting on a horizontal surface, and the horizontal frictional force is 12 N, what is the acceleration? 2- A 400 kg lion grasping a vertical tree slides down at a constant velocity.  What is the friction force of the tree?  (Hint: Constant velocity means zero acceleration, and therefore zero net force) 3- True or False: According to Newton’s Third Law of Motion, if object A exerts a force on object B, then object B exerts a force on object A. thank you in advance
