Question

A particle is moving with a constant velocity of \( 5 \, \text{m/s} \) in a circular path of radius \( 2 \, \text{m} \). What is the centripetal acceleration of the particle?

• A. \( 1.25 \, \text{m/s}^2 \)
• B. \(12.5 \, \text{m/s}^2 \)
• C. \( 5 \, \text{m/s}^2 \)
• D. \( 10 \, \text{m/s}^2 \)

Hint:

Remember: The centripetal acceleration depends on both the velocity of the particle and the radius of the circular path. It increases with the square of velocity and decreases with the radius.
