A car is moving in a circular path with a radius of 100 m. If its centripetal acceleration is 4 m/s², what is its speed?
Q1. A car is moving in a circular path with a radius of 100 m. If its centripetal acceleration is 4 m/s², what is its speed?
Answer: 20 m/s
Explanation: v² = centripetal acceleration * radius = 4 * 100 = 400, v = √400 = 20 m/s
