an object is represented by the dot on the motion map. which object is most likely represented by the dot? a car driving over the top of a hill a ball on a string that stopped at the top of a vertical loop a roller coaster car at the top of a vertical loop of track a bug on the top of a rolling hula hoop

an object is represented by the dot on the motion map. which object is most likely represented by the dot? a car driving over the top of a hill a ball on a string that stopped at the top of a vertical loop a roller coaster car at the top of a vertical loop of track a bug on the top of a rolling hula hoop

Answer

Brief Explanations:

Analyze the motion and forces for each option. A car over a hill has a different motion pattern. A ball stopped at the top of a vertical - loop has no centripetal motion at that instant. A roller - coaster car at the top of a vertical loop has centripetal force acting downwards. A bug on a rolling hula - hoop has a different motion as the hula - hoop rolls. The roller - coaster car at the top of the vertical loop has a downward acceleration due to gravity and centripetal force, which is consistent with the dot's representation.

Answer:

a roller coaster car at the top of a vertical loop of track
