Uniform Circular MotionQuiz - Solve & Score
Q1. A race car laps a circular circuit of radius 700 m once every 11 s. What is its speed in km/h (pi = 22/7)?
- A.111.11 km/h
- B.1440 km/h
- C.400 km/h
- D.720 km/h
Answer: B. 1440 km/h
speed = 2*pi*r/T = 2*22/7*700/11 = 400 m/s. Convert: 400 m/s * 3.6 = 1440 km/h.
Q2. A satellite of orbital radius 350 m circles once in 22 s. What is its orbital speed in km/h (pi = 22/7)?
- A.27.78 km/h
- B.100 km/h
- C.360 km/h
- D.180 km/h
Answer: C. 360 km/h
speed = 2*pi*r/T = 2*22/7*350/22 = 100 m/s. Convert: 100 m/s * 3.6 = 360 km/h.
Q3. A cyclist circles a circular park of radius 1400 m, one loop taking 44 s. What is the cyclist's speed in km/h (pi = 22/7)?
- A.200 km/h
- B.720 km/h
- C.360 km/h
- D.55.56 km/h
Answer: B. 720 km/h
speed = 2*pi*r/T = 2*22/7*1400/44 = 200 m/s. Convert: 200 m/s * 3.6 = 720 km/h.
