## Homework Statement

A motorist is traveling at 10m/s in a car whose maximum deceleration rate is 5.0 m/s^2

The effective reaction time between seeing a hazard and starting to brake is 0.5s

- Calculate the thinking distance for the drover ar this speed (ie the distance traveled during his reaction time)
- Calculate the minimim braking distance (ie the distance traveled during maximum deceleration)
- the total minimum stopping distance at 10 m/s
- The car approaches traffic lights at 12 m/s and the lights turn red when it is 20m from the line. Show whether it is possible for the car to stop before reaching the line and calculate how far from the line it will stop.

## Homework Equations

## The Attempt at a Solution

- s= 10 x 0.5 = 5m
- s= 10 x 2 x 1/2 x (-5) -> s= 10 m
