Textbook Question
Chapter 5.1, Problem 15E
Solve Problem 13 again, but this time assume that the springs are in series as shown in Figure 5.1.6.
Figure 5.1.6 Springs in series
13. A mass weighing 20 pounds stretches a spring 6 inches and another spring 2 inches. The two springs are then attached in parallel to a common rigid support in the manner shown in Figure 5.1.5. Determine the effective spring constant of the double-spring system. Find the equation of motion if the mass is initially released from the equilibrium position with a downward velocity of 2 ft/s.

2. A Ferris wheel has a radius of 40 feet and is boarded in the 6 o'clock position from a platform that is 5
feet above the ground. The wheel completes a counterclockwise revolution every 2 minutes. At t=0 the
person is at the 3 o'clock position.
Now measure and record the period for small angle motion with a stopwatch (there is no angle too small, so long as you can see it move). Measure the period in the following way: Move the mass away from equilibrium. Start a stopwatch and simultaneously release the mass. Stop the stopwatch after it swings 5 times back and forth. Record this value. Now acquire 5 more periods this way (each with five swings) so that you have six measures of the period of the same pendulum. Q2: What is the period of the pendulum written as mean +/- error while using a 95% confidence interval?
Measurement #1: 3.17 Seconds (Period - T=0.634)
Measurement #2: 2.95 Seconds (Period - T=0.590)
Measurement #3: 3.25 Seconds (Period - T=0.650)
Measurement #4: 3.16 Seconds (Period - T=0.632)
Measurement #5: 3.17 Seconds (Period - T=0.634)
Measurement #6: 3.22 Seconds (Period - T=0.644)
Mean = 3.784/6=0.630
I do not understand how to produce the error +/- while using the 95% confidence interval.
