He continues on for a while until he encounters a 500. kg boulder blocking his way. He puffs up his chest, crouches a bit, and begins to push horizontally with a force of 2,205 N. The coefficient of friction between the ground and the boulder was 0.450. Was he able to move it out of the way?
Tension: The force with which a string or rope pulls on an object is called the tension. This force always pulls along the direction of the string. Kinetic (Sliding) Friction: This force acts when two surfaces slide against each other. The force along the surface and is opposite the direction of relative sliding. Static Friction: This force may act when two surfaces are in contact without sliding relative to each other. The force is along the surface and has the direction and magnitude needed to keep the surfaces from sliding against each other. It is often difficult to determine the direction of this force. Free Body Diagrams To apply Newton's 2 law, you must correctly identify all the forces without overlooking any or adding any forces that do not act directly on the object. To do so, we will draw a "free body diagram" (FBD) which represent each outside force acting on an object by a labeled arrow. The labels represent the magnitude of the force, for example, "F" for the normal…
