N-mg=mv^2/r
N=6mg(given)
6mg-mg=mv^2/r
5mg=mv^2/r
Cancel out the mass on both sides since it is common
5g=v^2/r
Substituting the value of g and r
G= 10m/s^2 r =20 m
V= 31.6m/s
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 six times 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?

why does G equal 10. INn other words what do you do to get G
