The plan is to have you drop the rubber ball at the same moment your friend starts the timer. You friend will then stop the timer when the ball hits the ground. Let's say you are using a meter stick with the smallest increment being a millimeter and the stop watch application goes down to a tenth of a second. lfyour friend measures a drop time of 1.1 second when the ball dropped a distance of 3.807 m, what is the acceleration of the rubber ball and the calculated uncertainty of the acceleration? Note: the calculated uncertainty can be determined using, 1 2 2 5 _ 5y 6:: 6aa((?) +4(T) ) 2) What do you think would be a greater source of error, the calculated uncertainty of acceleration or your friends ability to accurately measure time
