Question

A particle moves with a constant speed of 4 m/s in a circular path of radius 2 m. What is its centripetal acceleration?

• A. 8 m/s\(^2\)
• B. 4 m/s\(^2\)
• C. 16 m/s\(^2\)
• D. 2 m/s\(^2\)

Hint:

Centripetal acceleration always points toward the center of the circular path and depends on the square of the speed and inversely on the radius. Double-check units to ensure correctness.
