Centripetal Acceleration on a Curve
Easycircular motionacceleration
A vehicle travels at 8 m/s around a circular path of radius 20 m. What is its centripetal acceleration?
- A0.4 m/s²
- B1.6 m/s²
- C3.2 m/s²
- D6.4 m/s²
Show solutionHide solution
Answer: C. 3.2 m/s²
The normal acceleration is an = v²/r = 8²/20 = 3.2 m/s², directed toward the center of the path.
