Question: What is the centripetal acceleration of a car moving in a circular path of radius 50 m at a speed of 20 m/s?
Options:
4 m/s²
8 m/s²
10 m/s²
16 m/s²
Correct Answer: 8 m/s²
Solution:
Centripetal acceleration is given by a_c = v²/r = (20 m/s)² / 50 m = 8 m/s².

What is the centripetal acceleration of a car moving in a circular path of radius 50 m at a speed of 20 m/s?
Centripetal Acceleration – Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.
Formula Application – The formula for centripetal acceleration (a_c = v²/r) requires correct substitution of values for speed (v) and radius (r).
