What percent error would be represented if the event in the previous problem took place over 10.0 seconds?

You are measuring the amount of time that it takes for an object to move a specified distance. You know that your own reaction time is approximately .3 seconds. What percent error would this represent, if the entire event you are measuring lasts 1.10 seconds?

Answer #1

error = 0.3 seconds

measured time = 1.10 sec

%error = ( 0.3/1.10) x 100 = 27.3%

if measured time is 10.0 seconds , error % will reduce substantially

% error = ( 0.3 sec /10.0) x 100 = 3 %

note: for this reason we are encouraged to measure the time period for large number of oscillations while doing simple pendulum experiment.

    What advice would you give to Ana in terms of pre-event sports nutrition? Athletes need to follow the upper limit of the suggested amounts on MyPlate. Ana’s meals should be eaten at least 2-3 hours before her event, and she should avoid foods that are high in fat, protein, or fiber for at least 4 hours before her event. Carbohydrates are the best source of energy for her running events. Athletes should follow the recommendations from MyPlate. Endurance athletes should...
