Question 3: A) A driver is traveling at an average speed of 40 kph when a person is crossing the road. If the perception reaction time of the driver is 2 sec., and the acceleration rate (a) is 5 m/sece', knowing that f, (a/g) calculate: 1. The safe S.S.D. on a level road. 2. The safe S.S.D. on a 3% uphill road. 3. The safe S.S.D. on a 2% downhill road.
