Braking function of a vehicle
From measurements, a quadratic function can model the braking distance (in meters), on a dry roadway, according to the speed (in km/h) that
the vehicle travels. The formula for the braking distance function is:
d (v) = braking distance (m) for a vehicle speed v (km/h).
d (v) = 0,005 v²
If a caravan driver on a freeway is at a distance of about 70 m from the vehicle in front of him, which must be its maximum speed (in km/h)? Truncate the solution to the units
