Applying Newton's Laws: Tension, Pulleys, and Systems — Homework
Find the whole system's acceleration first, then zoom in on one object to find an internal force.
- 1.Two blocks hang from a string over a frictionless, massless pulley: m1 = 6 kg and m2 = 4 kg. Find the system's acceleration and the tension in the string.
- 2.A 60 kg person stands on a scale in an elevator accelerating downward at 3 m/s^2. Find the scale reading.
- 3.A 4 kg block on a frictionless table is pulled by a 30 N force and drags a 6 kg block behind it via a connecting string. Find the system's acceleration and the tension in the string.
- 4.Explain why the tension is the same at both ends of an ideal string, even when a pulley changes its direction.
- 5.Describe a real system of two connected objects (a tow rope between two cars, a sled pulling another sled) and explain how you would find their shared acceleration.
