Homework Statement
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?
Homework Equations
F = mdv/dt
KE = (ma^2)/2
F = KE/d
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 traveled after impact.
How can an impact force be calculated simply by knowing material properties, mass of falling object, and distance of fall?
Thanks.
