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...

90 m (15 points) A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A. rolls with negligible friction down the incline and follows the track around a loop of radius 20 m. Point B. the highest point on the loop, is at a height of 50 m above...

A car in an amusement park roller coaster ride rolls without friction at the top of a hill. The car begins at a height h from the top of a hill. A the bottom, the car then goes through a vertical loop where the car is upside down at the loop\'s top. If the radius of the loop is 20.0m, what is the minimum height h such that the car moves around the loop without falling off the track at...

A roller coaster accident occurs at an amusement park. An engineer happens to be in the park at the time of the accident. A reporter finds out the person is an engineer and asks her to speculate on the cause of the accident. Which of the following actions may the engineer take and still be ethical? 6 I. The engineer may speculate on the cause of the accident as long as she qualifies the remarks as speculation. IL. The engineer...

You are designing a new roller-coaster. The main feature of this particular design is to be a vertical circular loop-the-loop where riders will feel like they are being squished into their seats even when they are in fact upside-down (at the top of the loop). The coaster start at rest a height of 80m above the ground, speeds up as it descends to ground level, and then enters the loop which has a radius of 20m. Suppose a rider is...

The mass of a roller-coaster, including its passengers, is 500.0 kg. The radius r 2 of the highest track (point B) in the figure is 40 m. Find the speed of the roller-coaster when the passengers feel weightless at the the top of the track. Weightless is the condition when the contact force between the coaster and the track is zero, that is, the normal force is zero. Use g = 10 m/s. 20 m/s 10V3 m/s 10 m/s 10v5...

6. Kingda Ka Roller Coaster (30 points) a) (6 pts) Ignoring friction, sketch a diagram showing the centripetal, gravitational, and normal forces acting of the passenger train of the Kingda Ka roller coaster as it rounds the bottom of the “Big Dip.” Draw each force with its correct direction. Draw the largest force as the longest vector, and the smallest force as the shortest vector.d) (6 pts) Ignoring friction, sketch a diagram showing the centripetal, gravitational, and normal forces acting of...
What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 20.0 m and the downward acceleration of the car is 1.50 g?
Modern roller coasters have vertical loops like the one shown in the figure below. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 20.0 m and the downward...
