Q
What is the value for an estimate of reaction time?
A
0.2s
2
Q
Thinking distance formula
A
Speed x time
3
Q
Reaction time formula
A
find out final - initial velocity by doing 2 x acceleration x distance which is equal to it.
then find out average speed by doing final + initial / 2.
then do time + distance/ average speed.
4
Q
Braking distance formula
A
re arrange the final - initial = acceleration formula (not full formula)
for distance.
5
Q
Stopping distance formula
A
thinking distance + braking distance
