Question

Consider a train that rounds a banked curve with a radius of 189 m at a speed of 26.9 m/s. The track is inclined at an angle of 3.1 degrees towards the center of the curve. What is the frictional force on a passenger on the train with mass 99.9 kg in order for the passenger to remain stationary in the seat. Give your answer in Newtons to at least 4 significant figures to avoid being counted incorrect due to rounding.

Answer #1

A car rounds a 50 meter radius curve that is banked such that a
car rounding it does not need friction at a speed of 12 m/s. What
is the bank angle of the road?
The coefficient of kinetic friction between the tires and the
road is 0.5 and the coefficient of static friction between the
tires and the road is 0.8. If the same road were flat (instead of
banked), determine the maximum speed with which the coar could...

A 1600 kg car rounds a curve of radius 70 m banked at an angle
of 12°. If the car is traveling at 84 km/h, will a friction force
be required?
Yes friction force will be required, how much force?

A 1000 kg car rounds curve of radius 75 m banked at an angle of
15 degree, if the car is traveling at 100 km/h, will a friction
force be required? If so, how much and what direction?

A curve at a racetrack has a radius of 600 m and is banked at an
angle of 7.0 degrees. On a rainy day, the coefficient of friction
between the cars' tires and the track is 0.50. Part A. What is the
maximum speed at which a car could go around this curve without
slipping? Give answer as vmax= and m/s

a miniature steam train rounds a bend in the track at 5.0 m/s.
the curve has a constant radius of 9.0 meters. the engineer
conducting the train has a mass of 96 kg. a. calculate the
centripetal acceleration. b. calculate the centripetal force. c. if
the velocity of the train was increased to 8.0 m/s, what will be
the centripetal force acting on the engineer?
