Question

Draw approximate plots for the single hex nut’s position, velocity, and acceleration vs. time. Label your axes and include approximate numerical values.

Answer 1

Without the proper data that you have regarding the actual hex nut, there is not much we will be able to do for you here.

Answer 2

thank i will provide you with that

Answer 3

Materials
• String (2.5 m)
• 6 hex nuts
• Tape measure
• *Metal baking dish (pie plate, cookie sheet, etc.)
• Stopwatch
*You must provide
Procedure
1. For this experiment, you will have to stand on something tall enough for the length of string to be suspended.
Try a chair, a ladder, or stairs with an open railing to one side. Be careful that you are fully supported
with whichever method you choose.
2. Tie the nuts 40 cm apart along the length of the string, starting with one on the end (Figure 6.6a). Hold the
string over the pan so that the first nut is slightly above the metal surface.
3. Let go of the string and observe the resulting pattern of “clangs” as each nut hits. Do this several times to get
an idea for the pattern.
4. Keeping one nut on the end, change the spacing between each successive nut to follow the series: 9, 27, 45,
63, and 81 cm (Figure 6.6b). Drop the string several times to observe the new pattern.
5. Remove one hex nut from the string.
6. Drop a single hex nut from the height of the top of your head. Record how long it takes the hex nut to hit the
metal pan. Repeat two more times, and find the average:

Questions
1. What gives a falling object its acceleration?

2. What was the difference between the noise patterns produced by equally-spaced nuts compared to the second spacing given to you?

3. For the second nut spacing, show that the total distance from the end of string for each nut increases according to the linear kinematics equations.

4. Which of the weights had the highest velocity when hitting the cookie sheet? Calculate this velocity (in m/s) using the kinematics equations.

5. Using the time it took a single hex nut to reach the pan, calculate the height from which it was dropped. Is this accurate compared to your known height?

6. Say you have a very long string and want the hex nuts to hit the ground 1 second apart. Using the kinematics equations, determine the spacing for 5 nuts to hit with equal timing. How much string would you need?

7. Draw approximate plots for the single hex nut’s position, velocity, and acceleration vs. time. Label your axes and include approximate numerical values.

Answer 4

Did you do the experiment yourself? I think once you actually do the experiment, you should be able to have the data to plot the graph yourself. Or at least provide the data so we can assist you in plotting the graph.
