Question

How can you estimate the total stopping distance of a car using its speed?

Miqdaam Hamed Hassan · Accepted Answer

speed=20mp
thinking distance=6m
braking distance=6m
total=12
AS SPEED DOUBLES, THINKING DISTANCE DOUBLES, BRAKING DISTANCE TIMES 4 SO:
speed=40mp
thinking distance=12m
braking distance=24m
total=36
