- Consider the figure shown in the following figure. You are loweringtwo boxes, one on top of the other, down a ramp by pulling on a ropeparallel to the surface of the ramp. Both blocks move with constantvelocity of 10.0 [m/s]. The coefficient of kinetic friction between theramp and the lower box is 0.555 and the coefficient of static frictionbetween the two boxes is 0.750. A. Draw the Free-Body diagram of both blocks. Set the ?-axis parallel to the ramp. B. Write Newton’s 2nd law along the ? and ? directions for both blocks considering their state ofmotion (accelerations). C. What are the magnitude and direction of the frictional force on the upper box? D. What is the magnitude of the applied force? E. Determine the angle at which the top block will start to slide down the bottom block.Problem: A S0-kg box slides down an inclined plane made up of varlous materials.

The plank B is attached by a cord to the wall so that it is stationary relative to incline S. There is friction between plank B and block A, and between block A and incline S. 1. Draw diagrams of all the forces acting on block A and plank B. 2. If the coefficient of kinetic friction is the same between A and B and between S and A, determine its value (expressed it in terms of 0). 3. Find the tension in the cord.Fext N E An orange ball is subjected to a constant external force Fext (this force is constant in both magnitude and direction). The force Fext has a magnitude of 28.6 newtons and it is directed at an angle theta = 0 = 62.4 degrees north of due east (as shown in red above). While Fext is acting on the orange ball, somebody else grabs the orange ball and moves it a distance 1.22 meters to the east and 1.88 meters to the south. Calculate the work (in joules) that Fext did on the orange ball while it was being moved. (The sign, positive or negative, is important.)
