Question

Riders in an aμsement park ride shaped like a Viking ship hung from a large pivot are rotated back and forth like a rigid pendulum. Sometime near the middle of the ride, the ship is momentarily motionless at the top of its circular arc. The ship then swings down under the influence of gravity.

a) Conservation of energy
b) Circular motion
c) Centrifugal force
d) Linear acceleration

Answer 1

The subject of this question is Physics and the concept being discussed is Circular motion. The riders in the amusement park ride experience circular motion as the Viking ship swings back and forth like a pendulum. At the top of its circular arc, the ship is momentarily motionless due to the conservation of energy.

Step-by-step explanation:

The subject of this question is Physics. The concept being discussed here is Circular motion.

The riders in the amusement park ride are experiencing circular motion as the Viking ship swings back and forth like a pendulum. When the ship is momentarily motionless at the top of its circular arc, it is at its highest point in the motion. This is due to the conservation of energy, where the potential energy is highest, and there is no linear acceleration at that point.
