The first student should drop the meter stick at a random time and the second student should catch it as soon as possible. The algorithm to calculate the reaction speed is d = vt + ½at²where 1. d = distance in metres 2. v = initial velocity = 0 3. a = acceleration due to gravity = 9.81m/s² 4. t = time in seconds We need to manipulate d = vt + ½at² to give us an algorithm for t As v = 0 then vt = 0 therefore the algorithm is t = Sqrt(2d/a) Example 1. d = 9cm 2. t = sqrt(2 × 0.09 ÷ 9.81) 3. t = sqrt(0.01835) 4. t = 0.135 seconds The whole process takes between 150 and 220 milliseconds.
