- Find the size of the net force produced by a 3 N and an 10 N force in each of the following arrangements. (a) The forces act in the same direction.(b) The forces act in opposite directions.(c) The forces act at right angles to each other.4) PULLEY PROBLEM 1: ATWOOD'S MACHINE Two blocks, A and B, (ma = 3.5 kg and me=2.0 kg) are attached by a light string which is placed over a frictionless pulley as shown below. The blocks are released from rest as shown below. Find: a) the acceleration of the blocks b) the tension in the string (Ans: a) 2.7 m/s, b) 25 N) AIf an automobile moving along a road at constant velocity experiences a force of 400 N in the forward direction, how much frictional force opposes the car’s motion? Explain briefly.
- 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…6 ) Many people buy a coffee or other hot beverage on their way to work. For safety, the cup usually has a lid and is placed in a cup holder. Using Newton’s first law, explain why both of these precautions are necessary.A woman has a weight of 251 lb.
