Exercise 1
Complete the following exercises. 1mi=1609 m
100mi/h= m/s
mi/h= 300m/s
Exercise 2: Examining 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?
