Answer:
S(t)=
Step-by-step explanation:
We are given that
Th braking distance for a certain car moving at velocity v(in m/s) is given by

The velocity of car B(t) t seconds after starting =
We have to find the value for braking distance S(t) after t seconds.
To find the formula for braking distance we will substitute the value of velocity B(t) in place of v in D(v)
Substitute the value of velocity then we get
Then, we get
The formula for the braking distance S(t) after t seconds=
The formula for the braking distance S(t) after t seconds=
