The amusement park ride shown above takes riders straight up a tall tower and then releases an apparatus holding seats. This apparatus free-falls back to Earth and is stopped safely right above the ground. Which of the following indicates the magnitude of the gravitational force exerted on a rider of mass m on the way up and on the way down?

The normal force is not always parallel to the force of gravity The normal force is independent of the force of gravity The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity The normal force causes an acceleration and therefore does not interact with gravityarrow_forward
