Practice Questions
A car of mass 1000 kg moves on a circular track with a radius of 40 m. If the coefficient of friction is 1.28, the maximum velocity with which the car can be moved is:
1. \(22.4~\text{m/s}\)
2. \(112~\text{m/s}\)
3. \(\frac{0.64\times40}{1000\times100}~\text{m/s}\)
4. \(1000~\text{m/s}\)
