Inclined Planes with Friction Video Lessons

Concept

# Problem: The suspended 2.8 kg mass on the right is moving up, the 2 kg mass slides down the ramp, and the suspended 8 kg mass on the left is moving down. There is friction between the block and the ramp. The acceleration of gravity is 9.8 m/s2. The pulleys are massless and frictionless. What is the tension in the cord connected to the 8 kg block? 1. 42.5958 2. 33.0193 3. 45.1758 4. 39.8194 5. 46.3585 6. 36.7226 7. 43.7416 8. 35.4743 9. 38.1757 10. 42.0574
