(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A vehicle falls 20 mm back onto a smooth steel track after going over a bump. It has polyurethane wheels. Young's modulus is known for both wheels and track materials. What is the force exerted by the vehicle onto the track as it lands?

2. Relevant equations

F = mdv/dt

KE = (ma^2)/2

F = KE/d

3. The attempt at a solution

I've looked long and hard for a solution to this but all I found were equations (such as the ones above) that require either a pre-known time value for the collision or a pre-known value for distance travelled after impact.

How can an impact force be calculated simply by knowing material properties, mass of falling object, and distance of fall?

Thanks.
