A roller coaster has a “hump” and a “loop” for riders to enjoy (see picture). The top of the hump has a radius of curvature of 12 m and the loop has a radius of curvature of 15 m. (a) When going over the hump, the coaster is traveling with a speed of 9.0 m/s. A 100-kg rider is traveling on the coaster. What is the normal force of the rider’s seat on the rider when he is at the...
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...

A student with mass 58.0 kg rides on a roller coaster with a vertical loop. At the top of the loop the track has a radius of 19.7 m and the roller coaster moves at speed of 21.9 m/s at the top. Determine the normal force from the seat on the student at the top of the loop. Give your answer in newtons (N) and with 3 significant figures.

A student with a mass of m=60kg rides a roller coaster with a loop with a radius of curvature of r=6.0meters. What is the minimum speed the roller coaster can maintain and still make it all the way around the loop? (Other answers for similar problems solve using the law of conservation of energy. However, we have not learned that in our course yet, and have only reviewed uniform circular motion. Is there another way to solve this equation? does...

4) When sitting in a roller coaster going through a vertical loop of radius of 8.5 meters, your "ap- parent' weight is the normal force provided by the seat, while your "true" weight is the gravitational force (which is unluckily unchangeable at mg) a) How fast must you be moving at the top of the vertical loop to achieve weightlessness (i.e., to have no apparent weight)? b) If moving at the same speed on the bottom of the vertical loop,...

At the top of a looped section of roller coaster track, the car and rider are completely upside down. What information is necessary to calculate the minimum speed of the car that will prevent a rider from falling out of it? Assume the rider is not strapped into the car. A.) the radius of the loop, the mass of the rider. and the mass of the car b. the mass of the rider and the width of the track c....

You are designing the section of a roller coaster ride shown in the figure. Previous sections of the ride give the train a speed of 16.1 m/s at the top of the incline, which is 37.1 m above the ground. As any good engineer would, you begin your design with safety in mind. Your local government's safety regulations state that the riders' centripetal acceleration should be no more than n 1.69 g at the top of the hump and no...

A certain roller coaster design uses a vertical loop of radius 7.248 m. Assuming that the roller coaster remains on the track, what is the minimum speed of a car at the top of the loop? (HINT: In general, the centripetal force is the vector sum of the car's weight w and the normal force N exerted by the tracks. The value of N varies with the speed. The minimum value of N is zero, which occurs when the roller...
