1.2 Displacement, Velocity, and Acceleration
Multi-Unit
A car travels at speed \(v_x\) on a level road behind another car. The driver's reaction time is \(t_r\), and the coefficient of friction between the tires and the road is \(\mu\). Derive an expression for a safe following distance in terms of \(v_x\), \(t_r\), \(\mu\), and \(g\).
