    Height block reaches on accelerating quarter pipe

    Hmm, I think I got it The max height is simply the horizontal distance traveled by the small block in the large block reference frame. This distance was unspecified, but call it x_o. Thus, h_max=x_o. This will be a S.H.O, based won the equivilance princ, because the small block can't tell the...

    Height block reaches on accelerating quarter pipe

    Ohh, just w=∫F.dr? which you calculate for the circular section of the ramp. Then find the speed at the top of curved portion K.E=w-mgR (we don't have R, Ohh well).

    Height block reaches on accelerating quarter pipe

    So I guess, the question is how to find the velocity of the small block atop the curved portion of the ramp? There must be some way to find the work the large block is doing? then this work is simply w=K.E + U.E. We are looking for the max height, thus K.E=0. Then, w=mgh. Then how do I explain...

    Height block reaches on accelerating quarter pipe

    I understand that page up until tidal forces. I feel like after that is applied to rotation, which should not be relevantn (I should read the whole thing, but time is short!)? I don't know how to apply this to the given system. The acceleration of the large block in the inertial ref. frame...

    Height block reaches on accelerating quarter pipe

    errr. Not really. I am also working a problem involving rotational reference frames (i.e. coriolis, and centrifugal fictitious forces), but am confused by that too. I know about coordinate transforms... kinda. just things like x'=x+at, for an accelerating frame. I guess, I'm lost!

    Height block reaches on accelerating quarter pipe

    There is a .jpg attached with the diagram. I think the picture is worth 10^3 words. Let me know if you can't see this, or still unclear. Thanks.

    Height block reaches on accelerating quarter pipe

    Homework Statement A block in the shape of a quarter circle moves at constant acceleration across the floor. At some moment a small block of mass m, which is at rest with respect to the floor, is placed atop the horizontal part of the large block. There is no friction in this problem. Assuming...

    Find velocity of rocket that obtains more gas from gas cloud

    I am having a hard time describing this situation, and getting proper cancelations\simplifications. To start we need to find an equation describing the momentum... I think. This would look like. P = P_ship + P_exhausted fuel + P_gas cloud = 0 P_ship = (M_total)(v+dv) P_exhausted = (v_ship -...

    Find velocity of rocket that obtains more gas from gas cloud

    Homework Statement To solve this problem you will need to construct a differential equation. A picture of the situation will help. Ignore all gravitational forces. A Rocket ship of structural mass M and fuel mass m, begins at rest relative to a gas cloud. The ship burns fuel at the rate ω which...

    Majoring in physics and math....how do I land flexible job?

    Another Idea that I have is my school offers a 'Big Data Analytic's Certificate'... I don't know anything about this, but intend to talk to a couple of prof. about it. Does anyone know anything about the certificate...would it be worth an extra semester if need be?

    Majoring in physics and math....how do I land flexible job?

    I understand that my academic knowledge isn't all that tangible to the work force, and If I weren't going to grad school I of would probably done engineering to prepare myself for the workforce better. I just want a job that isn't in retail, or the restaurant business ...etc. I want a job that...
