The acceleration of the car is -4m/s^-2.
a) what distance does the sports car travel before the driver slams on the brakes?
Thats adjectives!
I think the answer is 20m but i m not sure!
Answers: I would hold said 20m but then I saw the acceleration of -4m/s...
So... coup¨¦ initially travelling at 40m/s, in another partially a second with a -4m/s acceleration it is travelling at 42m/s. Which medium the average speed over that half second is 41m/s - giving a distance travelled of 20.5 metres.
I'm in principle sure 20.5 metres is the correct answer.
