16. Reaction time tests can be used to assess an individual's hand-eye coordination. One test involves catching a 1 metre ruler
and measuring the distance, din metres, that the ruler travelled before being caught. The reaction time t seconds is then calculated using the formula: 2d t = 9.8 2d d (a) Simplify the expression under the square root sign to 9.8 ?
Answer:Reaction time tests can be used to assess an individual's hand-eye coordination. One test involves catching a 1 metre ruler and measuring the distance, d in metres, that the ruler travelled before being caught. The reaction time t seconds is then calculated using the formula: = √2d/9.8.
