Questions 111
Question 1: Table (Use F = m*g, and k = F/x)
Question 2: DeltaT = .5*(Deltak/k)*T
Question 3: Table (T_theor = 2*pi*sqrt(m/k), and DeltaT_theor = .5(Deltak/k)*T_theor)
Question 4: Graph, find slope
Question 5: Use equation: (Your slope  1)/(Error of slope)
Question 6: Table
Question 7: v_0 = w/t
Deltav/v = Deltaw/w
Question 8: DeltaPE_max = sqrt((Deltak/k)^2+(2*Deltax/x)^2)*PE_max
Question 9: DeltaKE_max = 2*(Deltaw/w)*KE_max
Question 10: Table
Question 11: Use equation: (PE_max  KE_max)/(sqrt(DeltaPE_max)^2 + DeltaKE_max)^2))
And you're done! Now wasn't that easy?

m=kg
x=m
f=N
k=N/m
M=kg
t=s
width=m
v=m/s
PE+KE=J
for the slope since it's s/s, i guess it should be none~
hope this helps

Re: leb report 7 execution
for number 4
my slope was .170
so which error sounds more right, .01 or .001?

hey
do we need to make graphs? cause there are no graph papers, and my TA didn't mention anything about graphs !!

ques10
for ques 10, when calc Pe_max what do we use for x_0 (initial/equilibrium position)?

question 8
I'm using DeltaPE_max = sqrt((Deltak/k)^2+(2*Deltax/x)^2)*PE_max, but it's not working..am I doing something wrong?

graph
quick question... for the graph, which goes on the x axis and which goes on the y axis?
meeeeeee Guest
Question 3
I'm having problems calculating the T_Theor. I know the formula is 2*pi*sqrt(m/k). i know the mass is suppose to be the glider and attached mass. but everytime i try it i get it wrong. can someone offer ideas on what i might be doing wrong...

Re: leb report 7 execution
For the graph you should have a solid "best fit" line and then dashed lines showing the error. As for the error bar you only need to draw them for the T_{theor} I believe, which ever the manual says.
Try calculating the sqrt(m/k) first then multiply it by (2pi).
As for axis labels try looking through previous posts (Hint: It's a few before this one)

Re: leb report 7 execution
are u sure about this??
X is Tmeas and Y is Ttheor
cause i get the slope wrong this way
when ireverse it i get t right ??

r u sure Guest
ques 7
i keep getting #7 wrong for some reason, around what time values did you guys get for the first velocity? i think i may have wrote mine down wrong..or around what value worked in maple ta for you?
