Answer:
Deceleration = units/sec^2
Step-by-step explanation:
Given that a car is traveling at when the driver sees an accident m ahead and slams on the brakes.
i.e. if he is coming with speed v units/sec say, he has to make his velocity 0.
Distance travelled = m units
Initial velocity = v
Final velocity =0
Use the third formula as
So he has to apply an acceleration of units/sec^2 to stop the car in time to avoid a pile up.
Deceleration = units/sec^2
First you would convert it to a fraction. 9/100
Once you do that you divide the numerator, which is 9 by the denominator, which is 100.
Then we get our answer, 0.09
