On all problems below, ignore wind resistance. 1. A car is traveling at a constant speed of 28 meters per second. It begins braking at 4 m/s/s.
(a) How long does it take to come to a stop? (b) How far does it travel in that time?

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

correct answer is c. just did it

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
