## Homework Statement

passengers cannot have a normal force equal to 0 or greater than 4 times their weight. What are the heights H1 and H2. Coaster starts at H1 and and ends at H2. H1>H2 and there is a low point between the two hills defined as zero height. The radius of the curve at the low point is 15m and the curve of the second hill H2 is 15m. Friction is to be neglected.

## Homework Equations

sum of the F= mv2 /r

conservation of mechanical energy k1+U1=k2+U2

## The Attempt at a Solution

Fc+N-mg = mv2 / r for the lowest point

Fc+mg-N = mv2 /r

I am unsure how to relate the constraints given to Newtons 2nd law for both hills and the conservation of energy.

Thank you for all insights
