Answer: acceleration = -10m/s^2

Explanation:
Use Fab 5 equation to solve for acceleration. (Use equation without d/distance because it is irrelevant for this particular question)

vi = 60m/s
vf = 0m/s because car comes to a stop
t = 6s
a = ?
d = irrelevant

Use a = vf-vi/t

Step by step solution:

a = vf - vi / t
a = 0 - 60 / 6
a = -60 / 6
a = -10m/s^2

Hope this helps! :)

Answer:

[tex]\boxed {\boxed {\sf a= -10 \ m/s^2}}[/tex]

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

[tex]a=\frac{v_f-v_i}{t}[/tex]

The car came to a stop, so it's final velocity is 0 m/s.

The initial velocity of the car is 60 m/s.

The time is 6 seconds.

[tex]v_f=0 \ m/s\\v_i=60 \ m/s\\t= 6 \ s[/tex]

Substitute the values into the formula.

[tex]a=\frac{0 \ m/s-60 \ m/s}{6 \ s }[/tex]

Solve the numerator.

  • 0 m/s-60 m/s= -60 m/s

[tex]a\frac{-60 \ m/s}{ 6 \ s }[/tex]

Divide.

[tex]a= -10 \ m/s^2[/tex]

The acceleration of the car is-10 meters per square second. The negative acceleration indicates it is slowing down/stopping.
