An engineer is designing a roller coaster for an amusement park. It is required that when the car goes over the top of a curved vertical section of trackat 6.0 m s 1 passengers feel "weightless" - that is, they feel they are "floating" out of their seats. 4 Draw a diagram that shows the forces acting on a passenger at the top of the track. (a) (b) Calculate the radius of curvature needed for this section of track.
A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to twice her weight as she goes through the dip. If r = 20.0 m, how fast is the roller coaster traveling at the bottom of the dip?
A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to three times her weight as she goes through the dip. If r = 18.0 m, how fast is the roller coaster traveling at the bottom of the dip? The answer is NOT 26.56
1. A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to twice her weight as she goes through the dip. If r = 28.7 m, how fast is the roller coaster traveling at the bottom of the dip? 2. A 0.21-kg ball on a stick is whirled on a vertical circle at a...
Sandra Wilkens was a roller-coaster enthusiast who, along with others, attended the Harley Amusement park’s “Roller Fest,” a POP (pay one price) event featuring unlimited roller-coaster riding by all attendees. Sandra, 25 years old, paid the $50 admission fee and was, at the time of her fatal accident, riding the Superman, a wooden double-loop coaster. On the final loop, Sandra was thrown from the coaster and killed. Witnesses say she was standing in the coaster car as it approached the...
