Felipe drives his car at a velocity of 28 m/s. He applies the brake, which slows the vehicle down at a rate of 6.4 m/s2 and causes it to slow to a stop. How long does it take for the car to stop

Verified Answer :

For this case we have that the final speed is given by:


\(vf = a * t + vo
\)

Where,

a: acceleration

vo: initial speed

t: time

Clearing the time we have:

\(t = \frac{vf - vo}{a}
\)

Substituting values we have:

\(t = \frac{0 - 28}{- 6.4}

t = 4.375
\)

Answer:

it takes 4.375 s for the car to stop

Answer:

the answer is 4.4 on edgen.
