A body is thrown from the surface of the Earth at an angle alpha to the horizontal with the initial velocity v_0 . Assuming the air drag to be negligible, find: (a) the time of motion, (b) the maximum height of ascent and the horizontal range, at what value of the angle alpha they will be equal to each other, (c) the equation of trajectory y(x) , where y and x are displacements of the body along the vertical and the horizontal respectively, (d) the curvature radii of trajectory at its initial point and at its peak.
