Current Attempt in Progress
A car can be braked to a stop from the autobahn-like speed of 214 km/h in 160 m. Assuming the acceleration is constant, find its
magnitude in (a) SI units and (b) in terms of g. (c) How much time T, is required for the braking? Your reaction time T, is the time y-
require to perceive an emergency, move your foot to the brake, and begin the braking. If T, = 400 ms, then (d) what is the ratio T
Dark sunglasses delay the visual signals sent from the eyes to the visual cortex in the brain, increasing Tr. (e) In the extreme case i
which T, is increased by 100 ms, how much farther along the road does the car travel during your reaction time?
(a) Number i
(b) Number i
(c) Number i
(d) Number i
