Answer:

F = -3000 N

Explanation:

Given that,

Mass of the car, m = 200 kg

A roller coaster containing four cars is accelerating at -15 m/s²

We need to find the force exerted on the roller coaster to bring it to a stop. Let F is the force.

F = ma

Putting all the values,

F = 200 kg × (-15 m/s²)

= -3000 N

So, the force us 3000 N and it act in opposite direction.
