At point B:
N = normal force in down direction
Fc = centripetal force towards the center
Fg = force of gravity in down direction
Force equation is given as
N + Fg = Fc
N = Fc - Fg
At point C:
N' = normal force in Up direction
Fc = centripetal force towards the center
Fg = force of gravity in down direction
Force equation is given as
N' - Fg = Fc
N' = Fc + Fg
we see that the normal force at C is different from normal force B because of the force equations we have for the two cases.

A car in an amusement park roller coaster ride rolls without friction at the top of a hill. The car begins at a height h from the top of a hill. A the bottom, the car then goes through a vertical loop where the car is upside down at the loop\'s top. If the radius of the loop is 20.0m, what is the minimum height h such that the car moves around the loop without falling off the track at...
A proposed ride at the Valley Fair amusement park launches a roller coaster car up an inclined track. Near the top of the track, the car reverses direction and rolls backwards into the station. As a member of the safety committee, you have been asked to compute the acceleration of the car throughout the ride and determine if the acceleration of an object moving up a ramp is different from that of an object moving down the same ramp. To...
Part of a roller-coaster ride involves coasting down an incline and entering a loop 7.10 m in diameter. For safety considerations, the roller coaster's speed at the top of the loop must be such that the force of the seat on a rider is equal in magnitude to the rider's weight. From what height above the bottom of the loop must the roller coaster descend to satisfy this requirement? m 1 -11 points SerCP8 7.P.019. My Notes Ask Your Teacher...
A car in an amusement park ride rolls without friction around a
track (Figure 1). The car starts from rest at point A at a height h
above the bottom of the loop. Treat the car as a particle.
Figure 1:
PART A:
What is the minimum value of h (in terms of R) such that the car
moves around the loop without falling off at the top (point B)?
PART B:
If the car starts at height h= 4.30...
A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...
Part of a roller-coaster ride involves coasting down an incline and entering a loop 8.60 m in diameter. For safety considerations, the roller coaster's speed at the top of the loop must be such that the force of the seat on a rider is equal in magnitude to the rider's weight. From what height above the bottom of the loop must the roller coaster descend to satisfy this requirement? m
Part of a roller coaster ride involves coasting down an incline and entering a loop 6.40 m in diameter. For safety considerations, the roller coaster's speed at the top of the loop must be such that the force of the seat on a rider is equal in magnitude to the rider's weight. From what height above the bottom of the loop must the roller coaster descend to satisfy this requirement?
An engineer is designing a roller coaster for an amusement park. It is required that when the car goes over the top of a curved vertical section of trackat 6.0 m s 1 passengers feel "weightless" - that is, they feel they are "floating" out of their seats. 4 Draw a diagram that shows the forces acting on a passenger at the top of the track. (a) (b) Calculate the radius of curvature needed for this section of track.
A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to twice her weight as she goes through the dip. If r = 20.0 m, how fast is the roller coaster traveling at the bottom of the dip?
A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to three times her weight as she goes through the dip. If r = 18.0 m, how fast is the roller coaster traveling at the bottom of the dip? The answer is NOT 26.56
