If an object is dropped from a height, its downward speed theoretically increases linearly over time because the object is subject to the steady pull of gravity. Here are observational data on the speed of a ball dropped from a certain height at time x = 0: Time (seconds) X 0 0.2 0.4 0.6 0.8 Speed (m/sec) Y 0 1.92 3.58 6.01 7.88

Wait a sec, please. What's the objective of your question? I don't see one.

I dont understand what you mean?

It is simple, if I add the experimental points to the graph of the line of best fit, I get this drawing:

The objective is for me to solve my three remaning home-work problems
Michele_Laino
  • Michele_Laino
I think that, answer to question #10, is wrong, since you have to draw the experimental points only
Howard-Wolowitz
  • Howard-Wolowitz
question is aasking for the scatterplot i thought
Michele_Laino
  • Michele_Laino
yes! and a scatterplot is a plot of experimental points
Howard-Wolowitz
  • Howard-Wolowitz
i didnt mean that, I meant to say that your saying that your scatter plot works for question 10 and 12
Michele_Laino
  • Michele_Laino
no, please my plot is the answer to question #12 only. If from such plot you delete the straight line, then you get the corresponding scatter plot, which is the answer to question #10

here is the scatter plot:

ok I understand, so we just had to delete the line basically?
Michele_Laino
  • Michele_Laino
yes!

oHHHH ok i wsa confusing myself
Howard-Wolowitz
  • Howard-Wolowitz
Now, for question can we please take it step by step because I know we alredy did it but i was confused then
Michele_Laino
  • Michele_Laino
we can write these steps: 1) making a scatter plot 2) conjecturing of the linear relation \(v(t)=At+B\) and therefore, using the least square method, computing the values of both constants \(A,\;B\) 3) updating the scatter plot from point 1), adding the straight line of best fit from point 2)
