    Simple Harmonic Motion & a vertical spring

    Well I've tried a few things and I still haven't found the right method... I don't know of a way to relate the frequency and spring constant, so I tried using (mg/k)^2 as my value for v in 1/2mv^2 but it didn't leave me with anything useful... So I'm really not sure where to go from here

    Simple harmonic motion of a car

    Actually, I think I got it now.. What I was doing made sense to me but since I was so far off I thought I was applying the equations to the wrong situation, but it turns out I just hadn't thought the question over enough

    Simple harmonic motion of a car

    Ohhh I thought I was just way off... I had tried subtracting the change in L when m = 1000 kg, but I see now that I had to use m = 1200 kg and that gives me a 2.22 cm difference Thank you :D

    Simple harmonic motion of a car

    A 1000 kg car carrying two 100 kg football players travels over a bumpy "washboard" road with the bumps spaced 3.0 m apart. The driver finds that the car bounces with a max amplitude when he drives at a speed of 5.0 m/s. The car then stops and picks up three more 100 kg passengers. By how much...

    Simple Harmonic Motion & a vertical spring

    Homework Statement A spring is standing upright on a table with its bottom end fastened to the table. A block is dropped from a height of 3.0 cm above the spring. The block sticks to the top end of the spring and then oscillates with an amplitude of 10 cm. What is the oscillation frequency...

    Calculating a deriv using logarithmic differentiation

    Hello,This is my first crack at using log differentiation, but I can't seem to get too far with it... Use logarithmic differentiation to calculate the derivative for the following function: y = \sqrt{x}e^{x^{2}} (x^{2} + 1)^{10} lny = \frac{1}{2}lnx * x^{2}lne * 10ln(x^{2} + 1)...

    How do you find the derivative of xe^{x}?

    I came across a derivative question on my exam that involved finding the derivative of xe^{x} and I realized I wasn't sure what to do with it... I figured you could either use f'(x^{n}) = nx^{n-1} and come out with xe^{x} or maybe since x is a variable you need to use the...

    Finding equation to tangent line

    Yeah I'm familiar with the little limit symbol with the right arrow under it, obviously not familiar enough though... I do know where to find more information on it in my text though, thanks for showing me where to look!

    Finding equation to tangent line

    Hmm I'm not sure if I know what you mean, because I think I have fallen into a similar situation with a problem I was working on... The solution in this case is 2.. Find the slop of the tangent line to the parabola y = 4x - x^{2} at the point (1,3) m = \frac{f(x+h) - f(x)}{h} =...

    Finding equation to tangent line

    Ok, so I was going over this example again, and I've realized I'm not sure what is going on in that last step (where the last h is gone, seemingly at random)... Has 0 been substituted for h?

    Finding equation to tangent line

    Ohh right! Thanks! That's what I figured was going on but I was't keeping the brackets in the denominator, I don't know why I couldn't see that now!

    Finding equation to tangent line

    Hello, I'm having trouble understanding an example from my test and I would appreciate your help clarifying how to get from one step to the next. Problem: Find an equation of the tangent line to the hyberola y = 3/x at the point (3,1) Eqation: m = \frac{f(a+h) - f(a)}{h} m =...

    Solving Logarithm Overkill: Find Exact Value for ln(ln[e^{e^{5}}])

    Hello again! I have been working on this log, and the longer I work on it, the more confused I get! Here's the problem: Find the exact value for: ln(ln[e^{e^{5}}]) ---- Here's what I've tried so far: e(ln[e^{e^5}}]) e^{x} = ln(e^{e^5}}) e^{x} = e^{e^5}} e^{5} = (2.72)^{5}...
