A roller coaster containing THREE cars is accelerating at 10 m/s2 before it comes to an abrupt stop at the end of the ride. The mass of one car is 300 kg. How much force was exerted on the roller coaster to bring it to a stop?
O 30 N
O 900 N
O 3000 N
O 9000 N



Answer :

The force was exerted on the roller coaster to bring it to a stop F=ma

the forces are balanced

During a tug-of-war competition, neither team is able to gain an advantage. Which of the following explains the forces in this situation the forces are balanced, the forces are overcome by air friction, the mass of the rope cancels the forces being exerted on it, and the forces are unbalanced.

Roller coaster:-curler coaster, or rollercoaster, is a form of enjoyable experience that employs a form of multiplied railroad music designed with tight turns, steep slopes, and from time to time inversions. trip along the song in open vehicles and the rides are regularly observed in entertainment parks and theme parks around the world.

The force exerted on the roller coaster to bring it to a stop is 3000N, so the correct option is option (C).

In physics, a force is a power that can change the motion of an item. A force can purpose an object with mass to alternate its pace. Pressure also can be described intuitively as a push or a pull. A force has both value and path, making it a vector quantity.

A pressure is a push or a pull and it affects our each day lives because without force, people might not be capable of open and near stuff or lift up our arms or legs .

Calculation :

Given data : Mass (m) = 300kg

                    Acceleration (a) = 10m/s^2

so,

Force = mass * Acceleration

          = 300kg*10m/s^2

          = 3000 N
