Richard asks…what would be the meaning of a non-zero y-intercept to the graph of reaction distance versus speed?Nancy answers:A non-zero y-intercept is a physical impossibility: if the speed =0 (at X = 0), then the reaction distance must = 0 (Y = 0).George asks…How to calculate overall stopping distance?How do I calculate overall stopping distance if:
Stopping distance = reaction distance + Braking distance
Stopping distance = 20.004m + breaking distance
Speed traveled is 60km/h or
