A roller-coaster track has six semicircular "dips" with different
radii of curvature. The same roller-coaster cart rides through each
dip at a different speed.For the different values given for the radius of curvatureR and speed v,

The roller coaster in Figure P6.36 starts with a velocity of 15
m/s. One of the riders is a small girl of mass 40 kg. At points B
and C, the track is circular with the radii of curvature given in
the figure. The heights at points A, B, and C are hA= 24.9 m, hB =
34.75 m, and hC=0 m. You may assume the track is frictionless.

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. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume 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...
