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.

1.Consider a roller coaster (m = 219.0 kg) at the lowest point on its track, where the radius of curvature is r = 20.0 m. If the velocity of the roller coaster is 16.0 m/s, calculate: (g=9.80 m/s2). Find the centripetal force. 2.Consider a roller coaster (m = 208.0 kg) at the lowest point on its track, where the radius of curvature is r = 24.0 m. If the velocity of the roller coaster is 23.0 m/s, calculate: (g=9.80 m/s2)....

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,

cart at the bottom of each dip.A) R=60m v=16 m/s B) R=15m v= 8m/s C) R=30m v= 4m/s D) R=45m v=
4m/s E) 30m v= 16 m/s F) R= 15m v=12 m/s

A roller-coaster car shown in the figure on the right is released from rest from a height h and then moves freely with negligible friction. The roller-coaster track includes a circular loop of radius R in a vertical plane. a. First suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height h of the release point above the bottom of the loop in...

1731 You have been hired to design a roller coaster. The information you are given is the speed of the roller coaster at various points (we will learn how to easily calculate that in Module 3) and the normal force on a rider. The normal force is typically given in terms of g's the rider experiences. For example if the rider were experiencing 0.4g, the normal force would be their mass times 0.4g. The advantage of expressing the normal force...
