    Finding the dampening constant

    The suspension (four springs) of a mass 2,603 kg car sags a distance of 23.2cm when the entire weight of the car is placed on it The effective amplitude decays to 51.6% of its initial value in 4 oscillations (exact). What is the value of the damping constant b of one of the springs (in kg/s)...

    Amplitude of Sinusoidal Motion for 0.269 kg Mass on 80.3 N/m Spring

    An object with mass 0.269 kg is hung on a spring whose spring constant is 80.3 N/m. The object is subject to a resistive force given by -bv, where v is its velocity. The ratio of the damped frequency to the undamped (natural) frequency) is 0.849. If this system is subjected to a sinusoidal...

    Measuring g in the Indian Ocean with a Submarine Pendulum

    thanks for the help i got the answer last night, thank-you

    Measuring g in the Indian Ocean with a Submarine Pendulum

    it changes slightly but how do you calculate that

    Measuring g in the Indian Ocean with a Submarine Pendulum

    no that won't work, i still don't know how to use the fact that it is centripedal acceleration to my advantage (a=v^2/r) using that doesn't give me a value close to g or anything close to 9.81 to compare the subs accerations to

    Measuring g in the Indian Ocean with a Submarine Pendulum

    so take the speed we right now are going because of the Earth's rotation and divide it by the radius then add the speed of the submarine to the speed were going right now and find the difference between them

    Measuring g in the Indian Ocean with a Submarine Pendulum

    or do you mean constant motion I am so lost for this question

    Measuring g in the Indian Ocean with a Submarine Pendulum

    it undergoes centripcal acceleration but the equation for that is v^2/r

    Measuring g in the Indian Ocean with a Submarine Pendulum

    A scientist is making a precise measurement of g at a certain point in the Indian Ocean (on the equator) by timing the swing of a pendulum of accurately known construction. To provide a stable base, the measurements are conducted in a submerged submarine. It is observed that a slightly different...

    Simple Harmonic Motion (tuning fork)

    Q. the end of on of the prongs on a tuning fork that executes simple harmonic motion of frequency 1266 hz has an amplitude of 0.4944mm. find the speed of the end of the prong when the end has a displacement of 0.2037mm. okay i know that you use the v(t) equations and all but where does...
