Homework Statement



A car is elastically launched up a ramp and we are required to calculate the normal force of the car at certain heights up the ramp.

Homework Equations





The Attempt at a Solution


I am able to calculate the elastic potential energy of the car during launching and i know when it reaches the targeted height it will momentarily stop and at that point all the energy is Eg. I am to calculate the vertical height and i need the ø to find fn for at that point fn is mgcosø. Any ideas how i can solve and find fn for different positions on the ramp? Maybe i am thinking about this wrong.
Thank you for your help

What kind of ramp is this exactly?

EDIT: Just saw in the title that it's curve. Assuming you mean a loop, the hint is that you know what F = ma is.

I know when it reaches that certain height it will be at rest, so fnet is zero, so acceleration is zero. but i know at the beginning fnet is fx, fx = ma?
