I've got the answer for (a). It's k = 0.78 N/m.
I'm having problems with (b). I know that the equation of displacement in this case should either be :
x(t) = Asin(ωt + φ)
or
x(t) = Acos(ωt - φ)
where A = amplitudeFrom what I understand, both the equation above should give the same result as...
So the Bernoulli's Equation..
My question : Are the terms on the left hand side equal to the total mechanical energy? So can I rewrite this equation as ?
Thanks everybody for the reply :) . I've understood how to get the equation for acceleration of the bodies. I've also understood that T1 is equal in magnitude to T3. But the answer that I got doesn't seem to match the one given. Is it true for me to assume that the tension in the string...
The figure :
What I understand from the figure :
T1=m1a1
T2=m2a2
T3-m3g=m3(-a3)
- The three masses given all have different mass so each of them has different acceleration
- How do one substitute to obtain the answer for a3?
- I've tried to substitute to find the value of a3, but it seems...
So, I was in class listening to my lecturer when I notice something intriguing. I was looking at the reflection of a lamp on the screen of my calculator. I paid close attention to the colour of the light reflected of my calculator and realized that when I rotate my calculator by about 90 deg...
