Explanation:

2.59 x 10⁷ N

Explanation:

Initial Velocity of car, u = 54 km/h

Final Velocity of car, v = 0 km/h

Time taken by the car to stop, t = 6s = hr = 1.67 x 10⁻³ hr.

Mass of the car, m = 800 kg

We know that, Acceleration, a = = x 10³ = -32.33 x 10³

Now, Force, F = ma = 800 x -32.33 x 10³ = -25868.26 x 10³ = 2.59 x 10⁷N

Hope this helps.

only 7 points xd hehe
