Exercise 1

Complete the following exercises. 1mi=1609 m

100mi/h= m/s

mi/h= 300m/s

Exercise 2Examining how the ball’s average speed varies with time

Similar with the example 5 from lab manual page 65 (Procedure) or the HOL website “Exercise 2” calculate the average speed for every 2m of the 6m traveled by the ball:

V1= speed of the ball for the 0-2 m

V2= speed of the ball for the 2-4 m

V3= speed of the ball for the 4-6m

Exercise 3

What sources of error were involved in this experiment and how could the amount of error be reduced?
