Suppose the coefficient of static friction between box A and the floor is 0.4, as shown at right. The coefficient of static friction between box B and a different floor is 0.6, as shown below right. mA = mB = 10 kg. A horizontal 30 N force is applied to each box, and both boxes remain at rest. Is the magnitude of the friction force exerted on box A greater than, less than, or equal to that exerted on box B? The magnitude of friction force on A is greater than the magnitude of friction force on B. The magnitude of friction force on A is less than the magnitude of friction force on B. The magnitude of friction force on A is equal to the magnitude of friction force on B. There is not enough information to answer the question.

A freight train consists of two 7.00×105 kg engines and 50 cars with average masses of 4.50×105 kg. (a) What force (in N) must each engine exert backward on the track to accelerate the train at a rate of 2.00×10−2 m/s2 if the force of friction is 7.50×105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently trains are very energy-efficient transportation systems. (Enter the magnitude.) N (b) What is the magnitude of the force (in N) in the coupling between the 37 th and 38 th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines? (Assume both engines are at the front of the train.) N

An object is subjected to a friction force with magnitude 4.26 N, which acts against the object's velocity. What is the work (in J) needed to move the object at constant speed for the following routes? (a) the purple path O to A followed by a return purple path to O J (b) the purple path O to C followed by a return blue path to O J (c) the blue path O to C followed by a return blue path to O J (d) Each of your three answers should be nonzero. What is the significance of this observation? The force of friction is a nonconservative force. The force of friction is a conservative force.
