1. Question 1

   Q1. A car is moving on a circular track. If the coefficient of friction is 0.2, what is the maximum velocity for a radius of 50 m?

   • A) 10 m/s
   • B) √(g * r * μ)
   • C) 20 m/s
   • D) 5 m/s

   Answer: √(g * r * μ)

   Explanation: The maximum velocity is given by √(g * r * μ), where μ is the coefficient of friction.
