1) Show a calculation of both the speed and the acceleration of the stopper for the 4 Newton trial. SHOW YOUR WORK BELOW! 2) Make 2 graphs: a. Force versus speed. b. Force versus speed squared. c. Which graph shows a liner relationship? d. Draw a best fit line for both graphs and determine the slope of the linear relationship. SHOW YOUR WORK BELOW. 3) Using the slope of your best fit line, calculate the mass of the stopper and determine your % Error. SHOW YOUR WORK BELOW! 4) Suppose the string that we were using has a maximum strength of FT = 400N. Determine the maximum velocity that you could swing your stopper in a 0.5 m circle without it breaking. SHOW YOUR WORK BELOW! 5) Using your answer from question #4, calculate the frequency of the stopper at this speed. SHOW YOUR WORK BELOW! PROCEDURE: Stick 1 Set the radius of the circle (length of the string from the top of glass to middle of stopper) to be 0.5 m. 2 Carefully spin the stopper maintaining a constant force. 3 Time how long it takes to make 10 revolutions. 4 Calculate the speed of the stopper using the time for ten revolutions and the distance traveled during this time. The distance will be ten times the circumference of the circle. Enter the information below, including the squared value of the speed. 5 Repeat this procedure with the forces listed in the table below.
