Homework Statement
1) A driver is traveling at 25m/s when she spots a sign that reads "Bridge Out Ahead". It takes her 1.0 s to react and begin breaking. The car slows down at a rate of 3.0 m/s2. Luckily, she stops 5.0m short of the washed-out bridge.
(a) How much time was required to stop the car when she spotted the sign?
(b) How far was the driver from the bridge when she first noticed the sign(keep in mind her reaction time)
Homework Equations
The Attempt at a Solution
25 m/s / 3m/s2 = 8.3seconds + 1 second (reaction time) = 9.3 seconds.
b)
