A horse runs to the finishline at 39.6 km/h. The drivers reaction time is 0.2 s. The braking distance is 22.8 m. Determine the stopping distance.
Slide 10 - Open question
given: v = 39.6 km/h = 11 m/s (39.6 / 3.6)
t = 0.2 s
s1 = 22.8m
asked: stopping distance
Solution : reaction distance :
s2 = v x t = 11 x 0.2 = 2.2 m
Stopping distance : s1 + s2 = 22.8 + 2.2 = 25m
