- Two blocks rest on a frictionless surface as shown. The slope part has an angle of 40◦(A) Draw freebody diagrams for both objects.(B) Write out an equation for the acceleration of the lighter block. Leave all unknowns as letters and put in numerical values for all terms that you can.(C) Write out an equation for the acceleration of the heavier block. Leave all unknowns as letters and put in numerical values for all terms that you can.(D) Would it be possible to solve the system of equations you have written in parts (B) and (C) to find the acceleration? (If you have done everything correctly, it will be possible, but this question is asking about the equations you have written out. If you have done something incorrectly, you can get credit for realizing it.) You do not have to solve this system of equations.A coin of mass m is at rest on a book cover which is at an incline angle relative to horizontal at as shown in the figure. There is friction f between the coin and the surface of the book so that the coin does not slide down the cover of the book. 70 (A) Draw a free body diagram for the coin on the surface of the inclined book cover, including all forces acting on the block as vectors. Make sure to label the vectors. Include x and y axes in your sketch (feel free to draw axes in any orientation you would like). (B) Use Newton's second law to write equations for forces acting on the coin in x and y dimensions (separately) as a function of the frictional force f, the mass of the coin m, the gravitational constant g, and the angle of the incline 0. (C) If the coin has a mass of 5.0 grams and the coefficient of static friction us is 0.37, find the maximum angle max such that the coin is stationary (ie does not slide).Sneak E. Fox Scheme #2: Hoist an Acme brand anvil into the air and drop it onto the bird, using a rope over a steel shaft. The anvil is made of steel and weighs 250 lbs. How much force on the free end of the rope does it take to hold the anvil in place? how much force on the rope is required to lift the anvil into place? is the fox able to hold the anvil using the rope? Can the fox lift the anvil using the rope?
- Problem 8: A crate of mass m =29.1 kg is in the bed of a pickup truck with the tailgate closed. There is Acceleration Tailgate negligible friction between the horizontal bed and the crate. The tailgate is vertical and contacts the back side of the crate. The truck accelerates forward on horizontal ground at a rate a =2.1 m/s². BedAnalyze the free-body diagrams (FBDs) and place them in the indicated order according to the magnitudes of their net forces.A hockey puck moving right is slowed down by friction as it slides across the floor. DRAW THE APPROPRIATE FORCE OR FREEBODY DIAGRAM.
- A beam of mass M and length L is hanging from a rope perpendicular to a wall. The rope is attached at a point that is 75% of the length of the beam. A second rope is attached to the end of the beam. On the second rope hangs a block with mass m. (a) Draw all forces acting on the beam in a free body diagram. (b) Write the equations necessary for equilibrium in terms of the forces for this situation. (c) Use the torque equation to solve for the tension.A car accelerates down a hill (see figure below), going from rest to 22.0 m/s in 8.40 s. A toy inside the car hangs by a string from the car's ceiling. The ball in the figure represents the toy, of mass 0.180 kg. The acceleration is such that the string remains perpendicular to the ceiling. (a) Determine the angle e. (b) Determine the tension in the string.
