pleae solve only number 3 Tension: The force with which a string or rope pulls on an object is called the tension. This force always pulls along the directionof the string.Kinetic (Sliding) Friction: This force acts when two surfaces slide against each other. The force along the surface and isopposite 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 thesurface and has the direction and magnitude needed to keep the surfaces from sliding against each other. It is often difficult todetermine the direction of this force.Free Body DiagramsTo apply Newton's 2 law, you must correctly identify all the forces without overlooking any or adding any forces thatdo not act directly on the object. To do so, we will draw a "free body diagram" (FBD) which represent each outside forceacting on an object by a labeled arrow. The labels represent the magnitude of the force, for example, "F" for thenormal force.2. A tennis ball of mass M is moving as shown after it has been struckby a racquet.

All the forces in the diagram shouldhave descriptive labels giving the name of the force, for example, "Tor"F" for the tension. Do not label the weight as "g" - this is theacceleration due to gravity and is not a force. Label the weight as "F","W", or "Mg".Newton's 3" law says that all forces come in action-reaction pairs, i.e., ifobject A exerts a force on B, object B must exert the same force on A but inthe opposite direction.
