Question
The following simple method can be employed to determine reaction time. A partner holds a meterstick by pinching it at the top and letting it hang vertically. To measure your reaction time, place your thumb and forefinger just below the base of the meterstick, ready to pinch it when it falls. Without signaling, your partner releases the meterstick; it accelerates due to gravity at a rate of 9.8 m/s2, and you grab it as fast as possible.
t = 0.14 s d = cm t = 0.16 s d = cm t = 0.18 s d = cm t = 0.20 s d = cm t = 0.22 s d = cmExplanation / Answer
assumuing g= 10 (a)s= (1/2)*g*t^2 reaction time = 0.089 sec (b) sd=98cm sd=128 cm sd=162cm sd=200cm sd=242cm
