    Angle of Impact: Calculating with Velocity & Distance

    Is this correct ? https://dl.dropboxusercontent.com/u/53341615/IMG_20150617_173554781.jpg This is actually a mathematics topic question and should somehow relate back to vector calculus

    Angle of Impact: Calculating with Velocity & Distance

    Homework Statement A ball rolls off a table at speed v and impacts the floor at distance d. What is the angle between the path of the ball and a vertical line drawn at the moment of impact. Homework Equations I have derived from basic projectile motion formulae: Time of impact t =...

    How to Calculate Frequency and Impulse Response?

    Think I got it...I can go from the freq response to impulse response by taking the inverse Fourier transform of the freq response.

    How to Calculate Frequency and Impulse Response?

    Hi, I have a discrete system with input x(t) and output y(t). Using the formula frequency response H(f) = y(f)/x(f) in the Fourier domain. Does this mean to find the frequency response I have to take the Fourier Transform of y(t) to get y(f) and divide it by the Fourier transform of x(t) ...

    Eigenvalues with an added part

    Homework Statement Hi, I have an electrical circuit, from which I have derived 4 equations to work out the current I of the circuit. To solve I need to put the equations into a matrix and find the eigenvalues & vectors, great I can do that. However there is an additional matrix on the end for...

    Engineering Solving Simple Circuits: Analyzing Currents Using Ohm's Law and Kirchoff's Laws

    Ahh thankyou very much. I was messing around with equations I didn't need. I just wrote out the Ohms, KCL & KVL equations then solved simultaneously, came out perfect. Once again, thanks :)

    How Can I Simplify This Boolean Expression Using XOR and XNOR Functions?

    For future reference (im not sure why anyone would care lol, but anyway), the equation can be simplified down to: W' (X⊕Y⊕Z)' + Y' (W⊕X⊕Z)' ...where (A⊕B⊕C)' represents a XNOR gate. This was obtained using karnough maps but I am sure there are easier ways...

    How Can I Simplify This Boolean Expression Using XOR and XNOR Functions?

    Hmm okay thanks, I've come up with this W' X' (Y⊕Z)' + W' X (Y⊕Z) + W Y' (X⊕Z) Is this on the right track..before I simplify further.
