Particle falls freely moving in the vertical $y-$direction. It starts with zero velocity at height $H.$ Upon reaching the ground, it bounces inelastically such that $v_y^{\text{'}}=-e{v}_y$ with $0$ a parameter. Using the EulerCromer method, write a Fortran code $to$ study the position and the velocity $of$ a particle $as$ a function $of$ time.
