1. Question 1

   Q1. A car is moving on a circular track with a radius of 100 m. If the coefficient of friction is 0.4, what is the maximum speed?

   • A) 10 m/s
   • B) 20 m/s
   • C) √(g * r * μ)
   • D) 40 m/s

   Answer: √(g * r * μ)

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