Chapter 5, Problem 1CQ
A car is moving forward slowly and is speeding up. A student claims that “the car exerts a force on itself” or that “the car’s engine exerts a force on the car.” (a) Argue that this idea cannot be accurate and that friction exerted by the road is the propulsive force on the car. Make your evidence and reasoning as persuasive as possible. (b) Is it static or kinetic friction? Suggestions: Consider a road covered with light gravel. Consider a sharp print of the tire tread on an asphalt road, obtained by coating the tread with dust.

Consider the figure shown in the following figure. You are lowering two boxes, one on top of the other, down a ramp by pulling on a rope parallel to the surface of the ramp. Both blocks move with constant velocity of 10.0 [m/s]. The coefficient of kinetic friction between the ramp and the lower box is 0.555 and the coefficient of static friction between the two boxes is 0.750.1. Write Newton's 2nd law of motion along the x and y directions for both blocks considering their state of motion.2. What are the magnitude and direction of the firctional force on the upper box?3. Draw the free-body diagram of both blocks. Set the x-axis parallel to the ramp.
Draw a diagram of the situation and label the givens in the problem: The cart's mass and the hanger's mass. Also label the direction of the cart and hanger's acceleration.
Draw two force diagrams. One for the cart and one for the hanger. You can treat the track as frictionless. Remember that the force in the string will be the same throughout the entire string.
Then define an x-y coordinate system and find the x and y components of the forces in your diagrams.
Two blocks are stacked as shown to the right and rest on a frictionless surface. There is friction between the two blocks (coefficient of friction μ). An external force is applied to the top block at an angle θ to the horizontal.
a)What is the maximum force F that can be applied for the two blocks to move together? Give your answer in terms of the variables from the problem statement in addition to g for gravitational acceleration.
