A car is moving in a circular path of radius 200 m on a flat road. If the coefficient of friction is 0.1, find the maximum speed.
Q1. A car is moving in a circular path of radius 200 m on a flat road. If the coefficient of friction is 0.1, find the maximum speed.
Answer: 10√2 m/s
Explanation: Frictional force provides centripetal force, so μ * m * g = (m * v²) / r. Thus, v = √(μ * g * r) = √(0.1 * 10 * 200) = 10√2 m/s.
