2. 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 five times her weight as she goes through the dip. of r = 21.5 m, how fast is the roller coaster traveling at the bottom of the dip?

Explanation:

Given

Passenger feels the seat of the car Pushing upward with a force equal to five times her weight

Therefore

it is given

where N=normal reaction

thus

a and c

c is 100% but i am confused in a

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
