Expand the following: \begin{align} &\cssId{Step1}{{s=?}}\\[3px] &\cssId{Step2}{→p_E= 12 b }\\[3px] &\cssId{Step3}{→ Example Selectivitat → p_E= 12*b= 3,6 m }\\[3px] \end{align}

- In the first step we make the equation of the force breaking with mass and acceleration
- In the seconde step we make the equation of normal force and the gravity force
- In the third step we make the equation of accelation with Force breaking and mass
