A body is thrown from the surface of the Earth at an angle α to the horizontal with the initial velocity v0. 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 α 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.
Solution:
