School Zone Stopping Distance
Loading…
Drive a test car past a school in 3D and press the brake yourself when a cardboard test dummy darts out from behind a parked car, measuring your own reaction time. See how speed, road surface, vehicle mass and phone use change the reaction and braking distances through the area under the v–t graph and a high-speed multiflash photo analysis of uniformly accelerated motion.
