Sliding Mass Problems Draw a force diagram and label the known information for each problem. Use your diagrams to write a valid equation for Newton’s Second Law and solve for the unknowns. You will need to use other equations (form Chapter 5) to solve. 1. A loaded snow sled is pulled by six huskies with a force of 1,250 N. Given that the mass of the sled is 500 kg and μ is 0.01, determine: A. Normal force B. Force of friction C. Acceleration of the sled D. Given that it started at rest what would be its velocity after it traveled 20 seconds E. How far did it travel in the first 20 seconds? 2. A person pushes a 500 kg crate with a force of 1200 N and the crate accelerates at 0.5 m/s 2 , determine: A. Friction force B. Normal force C. μ (coefficient of friction) D. What would be the velocity at 10 seconds (given it started at rest)?

Unformatted text preview: E. How far did it travel in the first 10 seconds? 3. A 50 kg sled is pulled by a force of 100 N that produces a constant velocity of 2.5 m/s, determine: A. the acceleration B. force of friction C. the net force D. μ E. F N 4. A 750 N crate is pulled by a rope with a tension of 500 N. If the new force is 200 N, determine: A. Force of friction B. μ C. acceleration 5. The coefficient of sliding friction is 0.02 between a crate and the floor. If the tension force pulling the crate is 500 N and the net force is 300 N, determine: a. force of friction b. normal force c. mass of crate d. acceleration of the crate e. what is the velocity of the crate (if it started from rest) after 2 minutes...
