A piston of mass 4.53(kg) is travelling in a tube with a velocity of 15.24(m/s). It engages a spring of stiffness 350 (N/cm) and a damper with a coefficient of 1.75 (N.s/cm)

What is the maximum displacement of the piston and how long does it take to reach this point?

## Homework Equations

F= -kx

where

x is the displacement vector - the distance and direction in which the spring is deformed

F is the resulting force vector - the magnitude and direction of the restoring force the spring exerts

k is the spring constant or force constant of the spring.

velocity=displacement/time

Damping : http://en.wikipedia.org/wiki/Damping

## The Attempt at a Solution

I have the solutions, Max. Displacement = 128.6(mm), Time Taken = 0.0157(s). I am stuggling to find a link between the known data and the displacement. Hope you can help
