Most of the standard textbooks and many teachers of Applied Mathematics make use of a velocity-time graph to facilitate the solution of elementary kinematical problems including vertical motion under gravity, but it is unusual to extend the method to projectiles and allied problems, in spite of the ease with which the more usual type of problem can be solved. Such problems may be solved by simple calculations based upon the properties of similar triangles and the areas of rectangles, triangles and trapezia, that is, by the normal velocity-time graph procedure.
