A typical reaction time for most drivers is approximately 1.00 s. The ability of vehicles to slow down varies greatly; however, traffic safety engineers often use a value of 5.85 m/s², backward to determine the minimum stopping distance for a vehicle on smooth, dry pavement.
Using the above information, determine the stopping distance for a typical driver if they are initially driving with a speed of 110 km/h. Be mindful of significant digits
