Question:
A roller-coaster car has a mass of 1200 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 18 m, its speed is not changing. At the top of the hill, what are the
(a) Magnitude Fry and
(b) Direction (up or down) of the normal force on the car from the track if the car's speed is v = 11 m/s? What are?
(c) FN and
(d) The direction if y = 14 m/s?
Step by Step Answer:
We will start by assuming that the normal force on the ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
