A ferris wheel with a radius 10 m makes 2 rotations in 4 minutes. What is the speed of the ferris wheel in meters per second.
**
2 rotations in 4 minutes= 1 rotation in 2 minutes=1 rotation in 120 seconds
In one rotation, ferris wheel travels the circumference=2π*radius=20π
speed=distance traveled/travel time=20π/120=π/6 m/sec
ans:
Speed of ferris wheel=π/6 m/sec
