Select the correct answer.

A roller coaster car is loaded with passengers and has a mass of 500 kg along with a speed of 18 meters/second at the dip. The radius of curvature of the track at the bottom point of the dip is 12 meters (gravity = 9.8 meters/second²). What force is exerted on the roller coaster car by the track at the bottom of the dip?

1.6 10⁴ newtons

1.8 10⁴ newtons

0.5 10⁴ newtons

1.0 10⁴ newtons

8.6 10³ newtons
