The wheels of a midsize car exert a force of 2100 N backward on the road to accelerate the car in the forward direction. If the force of friction including air resistance is 250 N and the acceleration of the car is 1.80 m/s2, what is the mass of the car plus its occupants? Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton's laws of motion. For this situation, draw a free-body diagram and write the net force equation.
An American football lineman reasons that it is senseless to try to out-push the opposing player, since no matter how hard he pushes he will an equal and opposite force from the other player. Use Newton’s laws and draw a free-body diagram of an appropriate system to explain how he can still-push the opposition if he is strong enough.
The force on a baseball as with a bat can be more than 8,000 lb. No human can push on a bat with that much force. What is happening in this instance?
. A person stands on a scale inside an elevator at rest (Figure 2.54). The scale reads 800 N. (a) What is the person's mass? (b) The elevator accelerates upward momentarily at the rate of 2 m/s2. What does the scale read then? (c) The elevator then moves with a steady speed of 5 m/s. What does the scale read now?
A 63.0-kg sprinter starts a race with an acceleration of 4.20m/s2. What is the net external force on him?
. Under certain conditions, the human body can safely withstand an acceleration of 10 g. (a) What net force would have to act on someone with mass of 50 kg to cause this acceleration? (b) Find the weight of such a person in pounds then convert the answer to (a) to pounds.
Review. Three forces acting on an object are given by F1=(2.00i2.00j)N, and F1=(5.00i3.00j)N, and F1=(45.0i)N. The object experiences an acceleration of magnitude 3.75 m/s2. (a) What is the direction of the acceleration? (b) What is the mass of the object? (c) If the object is initially at rest, what is its speed after 10.0 s? (d) What are the velocity components of the object after 10.0 s?
What force is exerted on the tooth in Figure 4.38 if the tension in the wire is 25.0 N? Note that the force applied to the tooth is smaller than the tension in the wire, but this is necessitated by practical considerations of how force can be applied in the mouth. Explicitly show how you follow steps in the Problem-Solving Strategy for Newton's laws of motion. Figure 4.38 Braces are used to apply forces to teeth to realign them. Shown in this figure are the tensions applied by the wire to the protruding tooth. The total force applied to the tooth by the wire, Fapp, points straight toward the back of the mouth.
A 7.0-N force parallel to an incline is applied to a 1.0-kg crate. The ramp is tilted at 20 and is frictionless. (a) What Is the acceleration of the crate? (b) If all other conditions are the same but the ramp has a friction force of 1.9 N, what is the acceleration?
If the acceleration of a system is zero, are no external forces acting on it? What about internal forces? Explain your answers.
As a horse and wagon are accelerating From rest, the horse exerts a force of 400 N on the wagon (Figure 2.56), Illustrating Newton's third law, the wagon exerts an equal and opposite force of 400 N. Because the two forces are in opposite directions, why don't they cancel each other and produce zero acceleration (i.e., no motion)?
A concept map is a visual representation of concepts and their connections. Create a concept map including the five specific forces listed in Table 5.1 and the four forces discussed in Section 5.10. Justify the placement of each force.
