SUMMARY

The discussion focuses on calculating the normal force (fn) of a car launched elastically up a curved ramp. The participant successfully calculates the elastic potential energy and recognizes that at the peak height, the car's energy is entirely gravitational potential energy (Eg). To find the normal force at various heights, the participant needs to determine the angle (ø) and apply the formula fn = mgcosø. The conversation highlights the importance of understanding the forces acting on the car, particularly in a looped ramp scenario.

PREREQUISITES
  • Understanding of elastic potential energy and gravitational potential energy
  • Familiarity with Newton's second law (F = ma)
  • Knowledge of trigonometric functions related to angles on ramps
  • Concept of normal force in physics
NEXT STEPS
  • Study the relationship between gravitational potential energy and height on a ramp
  • Learn how to apply Newton's second law in non-linear motion scenarios
  • Explore the dynamics of circular motion, particularly in looped ramps
  • Investigate the effects of friction on normal force calculations
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of motion on curved surfaces, particularly in the context of elastic forces and normal force calculations.

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?
