x = v0t
на ось у
y = h - gt^2/2
Когда камень упал на землю, у = 0, поэтому h - gT^2 = 0, откуда T = корень из (2h/g), T - эо время полёта камня.
В момент времени T, координата х камня стала х = l
Значит l = v0T, откуда v0 = l/T = l / корень из (2h/g) = l * корень из (g/2h) = 14* корень из (9.8/20) = 14*корень из 0.49 = 14*0.7 = 9.8
