An automobile moves at a constant speed over the crest of a hill traveling at a speed of 85.7km.h. At the top of the hill a package on a seat in the rear of the car barely remains in contact with the seat. What is the radius of curvature (m) of the hill?
85.7km/h=2.38m.s v=2.38m/s ac=v^2/r r=v^2/a
I know that the only force acting on the package is gravity. Does this mean that the mass of the package is 9.80? mg=m*ac
I am not sure where to go from here
