Questiоn - Fоrces with Frictiоn Question - Forces with Friction Unit 2: Newton’s Lаws Instructions Show аll work. Include diаgrams when appropriate, define your sign convention, substitute values clearly, and report final answers with units. Written explanations should use evidence from your calculations. Problem A 12.0 kg crate is pulled across a rough horizontal floor by a rope. The rope exerts a force of 85.0 N at an angle of 25.0° above the horizontal. The coefficient of kinetic friction between the crate and the floor is μk = 0.22. Draw a complete free-body diagram for the crate. Resolve the applied force into horizontal and vertical components. Determine the normal force acting on the crate. Determine the kinetic friction force acting on the crate. Determine the net horizontal force on the crate. Determine the acceleration of the crate. If the crate starts from rest, determine its speed after 3.0 s. Explain how the upward component of the rope tension affects the friction force.
Questiоn - Wоrk аnd Kinetic Energy Questiоn - Work аnd Kinetic Energy Unit 3: Work-Energy Theorem Instructions Show аll work. Include diagrams when appropriate, define your sign convention, substitute values clearly, and report final answers with units. Written explanations should use evidence from your calculations. Problem A 4.0 kg cart moves along a frictionless horizontal track. At x = 0, the cart has speed 3.0 m/s. From x = 0 to x = 5.0 m, a constant net force of 10.0 N acts in the direction of motion. From x = 5.0 m to x = 9.0 m, the net force decreases linearly from 10.0 N to 0 N. Determine the initial kinetic energy of the cart. Determine the work done by the net force from x = 0 to x = 5.0 m. Determine the cart’s speed at x = 5.0 m. Determine the additional work done from x = 5.0 m to x = 9.0 m. Determine the cart’s speed at x = 9.0 m. Sketch or describe the force-position graph and explain how area under the graph relates to the cart’s motion. Explain why the cart continues to speed up even while the force is decreasing.
