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.

3. A frictionless roller-coaster goes around a circular loop of radius 11 m. It enters the bottom of the loop going 32 m/s. Find the speed of the roller-coaster when it gets to the top of the loop 4. For the loop in the previous problem find the velocity of the roller-coaster as a function of height off the ground. Use that to find the centripetal acceleration as a function of height. Plot the centripetal acceleration as a function of...

5. The picture shows the launch and first hills of a roller coaster. The cars are launched with some initial velocity, V, go down a hill of height h, = 4.36 m and over the first peak with height h2 = 6.77 m above the lowest point on the track. The shape of the first peak is a circle with a radius of R = 5.97 m. The ride is designed so that the riders feel weightless at the top...
