   * The final momentum of the puck is given by the update form of the [[183_notes:momentum_principle|Momentum Principle]]: $\vec{p}_f = \vec{p}_i + \vec{F}_{net} \Delta t$.   * The final momentum of the puck is given by the update form of the [[183_notes:momentum_principle|Momentum Principle]]: $\vec{p}_f = \vec{p}_i + \vec{F}_{net} \Delta t$.

Line 36: Line 35:
 $$\vec{p}_f = m_{puck}\vec{v}_f = \vec{F}_{net} \Delta t$$ $$\vec{p}_f = m_{puck}\vec{v}_f = \vec{F}_{net} \Delta t$$
  
-So that,+because the puck starts from rest. So that,
  
 $$\vec{v}_f = \dfrac{\vec{F}_{net}}{m_{puck}} \Delta t$$ $$\vec{v}_f = \dfrac{\vec{F}_{net}}{m_{puck}} \Delta t$$
