A The length of the roller coaster track is 100 ft and the elevation change of the track from point A, at the bottom of the track, to point B, at the top of the track is 20 ft. The roller coaster car, including the passengers, weights 1,200 lb, and the force of friction between the car and the tracks is 20 lb. The speed at point A is 45 ft/s. Determine the speed at point B. B Solve the...
1. Based on Problem 12.47 from the text. Suppose a roller coaster descends through a curve in a "vertical plane" (a) Initially the coaster rides along a segment with radius of curvature 30m. The speed of the car is 120 km/hr as it approaches point A. What is the normal force experienced by the rider relative to his or her weight just as it arrives at point A? Equivalently, how many "g's" is this? (b) After leaving point A, the...

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...
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 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...
