You are asked to do an experiment to measure g. You set up a device which drops a metal ball from rest from a height of 1.650m. Using an accurate timing device which detects the release of the ball and its landing on the floor, you measure the average time of the falling ball to be 0.585s.

a.
What do you measure the value of g as?
b.
Can you give an explanation as to the error from the accepted value of 9.8 meters per square second?
