An ice cube with a mass of 0.0507 kg is placed at the midpoint of a 1.00-m-long wooden board that is propped up at a 50 angle. The coefficient of kinetic friction between the ice and the wood is 0.133. a. How much time does it take for the ice cube to slide to the lower end of the board? b. If the ice cube is replaced with a 0.0507-kg wooden block, where the coefficient of kinetic friction between the block and the board is 0.275, at what angle should the board be placed so that the block takes the same amount of time to slide to the lower end as the ice cube does? You may find a spreadsheet program helpful in answering this question.
The shower curtain rod in Figure P6.7 is called a tension rod. The rod is not attached to the wall with screws, nails, or glue, but is pressed into the wall instead. Explain why the rod remains at rest, supporting the curtain. Explain why the name is misleading and come up with a better name. FIGURE P6.7
(c) A claw hammer can be used both to drive nails into a piece of wood and to get themback out (see figure 1b). The person in the image needs to exert a force of 50 Non the hammer to pull the nail loose. The handle is 25 cm long, and the distancebetween the handle and the head of the nail is 2.0 cm. Find the force the hammeris exerting on the wood (not the nail!). You may assume that the point where thehammer touches the wood is along the line of the handle. Hint: Start your answerwith a free-body diagram. May I have a detailed step by step explanation of this c) problem? Its for a hand in homework and I don't know how to solve it
Flying Circus of Physics Brake or turn? The figure depicts an overhead view of a car's path as the car travels toward a wall. Assume that the driver begins to brake the car when the distance to the wall is d=109 m, and take the car's mass as m=1430 kg, its initial speed as v0=39.0 m/s, and the coefficient of static friction as μS=0.500. Assume that the car's weight is distributed evenly on the four wheels, even during braking. (a) What magnitude of frictional force is needed (between tires and road) to stop the car just as it reaches the wall? (b) What is the maximum possible static friction fS, max? (c) If the coefficient of kinetic friction between the (sliding) tires and the road is μk=0.410, at what speed will the car hit the wall?

(d) What magnitude of frictional force would be required to keep the car in a circular path of radius d and at the given speed v0?…

Two blocks are stacked as shown. The blocks and the table are all of the same material; the coefficients of friction are μ s = 0.39 and μ k = 0.21. A horizontal force FA is applied to the lower block. The masses of the top and bottom block are 2.7 kg and 5.4 kg, respectively. Determine the maximum value of FA that can be applied without the top block slipping. (Answer in N.)
