hi guys i need help on a little subject.i have an aeroplane i want to launch of a platform 6m high using a large weight to catapult it . the plane will weigh 250 kg, i'm going to drop a large weight of 300 kg off the end of the platform so that is going to fall a max of 6m downwards . the plane will then be dragged horizontally along the platform. i can gear it using pulleys if necessary so it will travel twice as fast . but i'd like to know how fast we can get it please ,i realize wind drag will have an effect but a rough idea would be great . many thanks woody
