    A project that needs direction, on gravity, friction, acceleration & deceleration

    ok so that didnt go to well haha what I am thinking now is could I use PE = mgh assuming negligble losses as the ball changes its energy at the bottom of the curve. So I would now use the energy of the pin to replace the PE in PE = mgh that gives me height

    thinking the angular velocity is incorrect as time is not part of the equation in that post which is important

    A project that needs direction, on gravity, friction, acceleration & deceleration

    SO does that mean that the rotational and translational energy of the ball must be equal to or greater than the potential energy of the bowling pin that I worked out earlier. so far I have worked out the Inertia of the ball to be 79.597 ok so now I think that the minimum energy would look...

    as to how accurate and real life, not really just something pretty close that would give a good indication of what we needed. and yep minimum height is what we are after, just to prove mathmatically we need a height higher than it The hockey ball is because as well as hockey on ice we...

    lol it is a bit confusing yes, ok hockey ball is 71mm in diameter, and on a weighing scales 157.9g or base unit of mass 0.1579Kg. skittle/Pin = 1.595Kg Point of impact I don't know that distance but can put it up on here tomorrow morning, obviously we have a time difference being...

    A project that needs direction, on gravity, friction, acceleration & deceleration

    Hi yeah its all a bit confusing. Basically we are designing a machine that will knock a skittle down, to build it we have to meet certain requirments/constraints etc. One of those requirements is that the device we build will be one metre away from the skittle so that means that the exit of...

    Yep its a bowling pin USBC standard I believe

    A project that needs direction, on gravity, friction, acceleration & deceleration

    First off I don't believe this would be classed as a homework question, as this is an engineering design project problem and I haven't been to school for over ten years, however if I am wrong I apologise. My problem is:- The object I want to knock down is a skittle: h = distance from...
