Quiz zum Vortrag
In a demonstration, John used a bucket of water tied to a 1.3 m long rope. The bucket and water have a mass of 1.8 kg. John whirls the bucket in a vertical circle with a speed of 3.9 m/s. What is the tension force in the string at the top and bottom of the vertical circle? (g = 9.8 m/s²)
- Tension at the top = 3.4 N, tension at the bottom = 38.7 N
- Tension at the top = 4 N, tension at the bottom = 30 N
- Tension at the top = 3.4 N, tension at the bottom = 3.4 N
- Tension at the top = 3 N, tension at the bottom = 38.3 N
- Tension at the top = 0.34 N, tension at the bottom = 3.87 N
A 76-kg pilot at an air show performs a loop de loop with his plane. At the bottom of the 52-m radius loop, the plane is moving at 48 m/s. What is the normal force acting on the pilot?

- 4,000 N
- 3,367 N
- 2,623 N
- 745 N
