A car is moving in a circular path of radius 50 m on a flat road. If the coefficient of friction is 0.4, find the maximum speed.
Q1. A car is moving in a circular path of radius 50 m on a flat road. If the coefficient of friction is 0.4, find the maximum speed.
Answer: 14 m/s
Explanation: Frictional force provides centripetal force, so μ * m * g = (m * v²) / r. Thus, v = √(μ * g * r) = √(0.4 * 10 * 50) = 14.14 m/s.
