If a projectile is launched at a speed u from a height H above the horizontal axis, g is the acceleration due to gravity, and air resistance is ignored, its trajectory is. y = H + x tan θ − x 2 g 2 u 2 ( 1 + tan 2 θ), and its maximum range is. R max = u g u 2 + 2 g H. I would like to derive the above R max, and here's what I've done: WebNov 9, 2024 · More about S2 Data on sold house prices, such as the results above for Eastern Avenue Sheffield S2, is supplied to us via monthly updates from the Land Registry for England and Wales and from the Registers of Scotland for Scotland. couch mesh file
