A car is moving on a circular track with a radius of 100 m. If its speed is 40 m/s, find its centripetal force if its mass is 500 kg.
Q1. A car is moving on a circular track with a radius of 100 m. If its speed is 40 m/s, find its centripetal force if its mass is 500 kg.
Answer: 8000 N
Explanation: Centripetal force = (m * v²) / r = (500 * (40)²) / 100 = 8000 N, using F = (m * v²) / r formula.
