Ignore friction and air resistance. If the total mass of the roller coaster cars is 800kg, and the 50,000 N of gravitation force are acting on the roller coaster cars, what is the acceleration of the roller cars?

Force = (mass) x (acceleration) = ==> Newton #2

Divide each side by (mass), and then it says:

Acceleration = (force) / (mass)

Acceleration = (50,000 N) / (800 kg)

Acceleration (of gravity) = 62.5 m/s²

.

Now, the only question I have is: WHERE is this coaster?

The gravity there is almost 6.4 times Earth's gravity.

It's 2.5 times Jupiter's gravity, and 23% of the gravity ON THE SUN!

If you weigh 125 pounds on Earth, you would weigh 7,813 pounds in THAT place. You surely couldn't climb into the coaster or sit in a seat, and the coaster surely could not carry you.
