Homework Statement
An accident safety system uses a spring to absorb the energy of a car before the car collides with a bridge abutment.
The vehicle has a mass of 1000kg and the design calls for stopping a car moving at 5m/sec (11.2 mi/hr) in 0.5m.
Find the spring constant k
Homework Equations
F=kx -> k=F/x
The Attempt at a Solution
I am having trouble finding the force of the collision. It is needed to find k, is it not? I was thinking I may need to use a kinematics equation to do this and solve for the acceleration (deceleration in this case).
