I don't know much about this, but probably the reason why your teacher circled 300k is because of what's in the photo below. If you couldn't tell from the photo, its because 300k isn't negative. Anyway this is my guess, based on my limited knowledge.

A 1,500-kilogram car travelling at 10 meters per second (about 22 mph) strikes a parked car on the side of the road. If the car
Alona [7]

The force exerted on the parked car by the moving car is –30000 N

To solve this question, we'll begin by calculating the deceleration of the moving car. This can be obtained as follow:

Initial velocity (u) = 10 m/s

Final velocity (v) = 0 m/s

Time (t) = 0.5 s

<h3>Deceleration (a) =?</h3>

a = \frac{v - u}{t} \\\\ a = \frac{0 - 10}{0.5}\\\\a = \frac{- 10}{0.5}

<h3>a = - 20 m/s</h3>

Finally, we shall determine the force exerted by the moving car on the parked car. This can be obtained as follow:

Mass of moving car (m) = 1500 Kg

Acceleration (a) = - 20 m/s

<h3>Force (F) =.?</h3>

F = ma

F = 1500 × (-20)

<h3>F = -30000 N</h3>

NOTE: The negative sign indicate force is in opposite direction to the parked car.

Therefore, the force exerted on the parked car by the moving car is –30000 N
