Answer 2

Answer:

-2 m/s²

Explanation:

Given:

Initial velocity = 10 m/s (u)

Time = 5 seconds (t)

Final velocity = 0 m/s (As it finally comes to rest) (v)

To find:

Acceleration (a)

Using the first equation of motion which says:

V=u+at

where:

V= final velocity

u= initial velocity

a = acceleration

t = time

Substituting the above values:

0=10+a×5

-10=5a

a=$\frac{-10}{5}$

a= -2 m/s²

The acceleration of the car is -2 m/s²
