in a experiment to detrmine the acceleration of free fall 'g' a student attached a length of ticker tape to a metal ball. when the ball was released it fell to the ground pulling the tape through a ticker timer that printed 50 dots per second on the tape. the student measured lengths of tape to find the speed ofthe ball as it fell.
a. calculate the time taken for the timer to print 10 dots on the tape.
b. the student cut the tape into lengths with 10 dots each, starting at the end attached to the ball. would you expect the lenghts to increase,decrease or stay the same as the ball fell?
