2. [#232] Stopping distance A value commonly taken for the perception-reaction time of motorists is At = 1.5 s. Using this value, determine the total stopping distance for a car travelling at 30 m . s(two significant figures). In calculating the stopping distance, let's assume that the vehicle continues at its initial speed for At, then decelerates to rest. A reasonable value for the deceleration in braking is (constant) 8.0 m . s. Stopping distance = metres. (Hint: How many significant figures?)
