Part A A claw hammer is used to pull a nail out of a board. The nail is at an angle of 60° to the board, and a force Fi of magnitude 500 N applied to the nail is required to pull it from the board. The hammer head contacts the board at point A, which is 0.080 m from where the nail enters the board. A horizontal force F, is applied to the hammer handle at a distance of 0.300 m above the board. (Figure 1) What magnitude of force F2 is required to apply the required 500-N force (F1) to the nail? (You can ignore the weight of the hammer.) Express your answer using two significant figures.

8. A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp. a) What problem could occur if the coefficient of friction were too high? Your answer: O Packages would go too fast and could break at the end of the ramp. O Packages could slow down too quickly and stop before the end of the ramp. O Packages could break the ramp because gravity would increase. O Packages could bounce off the ramp because normal force would increase.
If you push a box across the floor its "physics work" but if you push on the wall it's not. Which of the following choices best explains why? Question 12 options: The direction of the force on the box is not the same direction as the motion. You're applying a force to the box but you are not applying a force to the wall. You're not applying a force to the box but you are applying a force to the wall. The box is moving but the wall is not.
Two blocks are connected by a string that goes over an ideal pulley as shown in the figure and pulls on block A parallel to the surface of the plane. Block A has a mass of 3.00 kg and can slide along a rough plane inclined 30.0 degrees to the horizontal. The coefficient of static friction between block A and the plane is 0.400. What mass should block B have in order to start block A sliding up the plane? ANSWER FORMAT: space EXAMPLE: 10.0 N В 30.0°

Delivering Rescue Supplies Review You are a member of an alpine rescue team and must get a box of supplies, with mass 2.40 kg, up an incline of constant slope angle 30.0 so that it reaches a stranded skier who is a vertical distance 3.40 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00x10-2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.01 m/s². Show Transcribed Text Part A Use the work-energy theorem to calculate the minimum speed u that you must give the box at the bottom of the incline so that it will reach the skier.
