Included Quiz Questions
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?
- 4,112 N
- 4,000 N
- 3,367 N
- 2,623 N
- 745 N
During the spin cycle of a washing machine, the clothes stick to the wall of the drum as it spins at 1,200 revolutions per minute. If the radius of the drum is 26 cm, what is the acceleration of the clothes?
- 4,106 m/s²
- 1,026 m/s²
- 104 m/s²
- 1,538 m/s²
- 1,067.5 m/s²
