## Sagot :

acceleration = change_in_velocity / time

so:

force = 740 kg * (19 m/s - 0 m/s) / 2.0 s

= 740 * 19 / 2 kg m per second^{2}

= 7030 kg m per second^{2}

= 7030 newtons of force

**Answer:**

Force exerted on the car is 7030 N.

**Explanation:**

It is given that,

Mass of the car, m = 740 kg

Initial speed of the car, u = 19 m/s

Final speed of the car, v = 0

Time taken, t = 2 s

Let F is the force exerted on the car during this stop. We know that it is equal to the product of force and acceleration. Mathematically, it is given as :

[tex]F=m\times \dfrac{v-u}{t}[/tex]

[tex]F=740\times \dfrac{0-19}{2}[/tex]

**F = -7030 N**

**So, the force exerted on the car during this stop is 7030 N. Hence, this is the required solution.**
