(a) A roller-coaster car has a total mass (including passengers) of 515 kg. Sitting in the car is a passenger with a mass of 51.0 kg. The car reaches the lowest point of a circular arc in the track, point A in the figure below, moving at a speed of 18.0 m/s. The radius of the arc is r₁= 25.0 m. What is the magnitude (in N) and direction of the force that the seat exerts on the passenger at point A? N magnitude direction. (b) What If? If the car has the same speed at point A as in part (a), what would the radius (in m) of the track have to be for the force of the seat on the passenger at this point to be four times the passenger's weight?

Question
Transcribed Image Text:(a) A roller-coaster car has a total mass (including passengers) of 515 kg. Sitting in the car is a passenger with a mass of 51.0 kg. The
car reaches the lowest point of a circular arc in the track, point A in the figure below, moving at a speed of 18.0 m/s. The radius of
the arc is r₁= 25.0 m.
What is the magnitude (in N) and direction of the force that the seat exerts on the passenger at point A?
N
magnitude
direction.
(b) What If? If the car has the same speed at point A as in part (a), what would the radius (in m) of the track have to be for the force
of the seat on the passenger at this point to be four times the passenger's weight?
