Use the kinematic equation - to solve for your reaction time, . The variable , initial velocity, is zero because you are releasing the meter stick from rest. So, the equation can be solved for time,

Use the kinematic equation - to solve for your reaction time, . The variable , initial velocity, is  zero because you are releasing the meter stick from rest. So, the equation can be solved for time, yielding an answer of where is the distance the meter stick fell through your grasp and  . 

1 In the table below, record the drop distances.  Make sure you convert the centimeter reading  to meters before entering the number in the table!
