Or do you know how to improveStudyLib UI? Without telling the test subject that you're going to do it, drop the ruler and the test subject catches it as quickly as they can between their fingers. 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 (For complaints, use Did you find mistakes in interface or texts? 3.
