In long jump, does it matter how height you jump ? What factors determine the span of the jump ?

Explanation

Yes, in olng jump it matters how high one jumps. It is explained below. For initial velcitu (u) and angle of projection `theta` the maximum height ,
`h=(u ^(2) sin theta)/(2 g) or u^(2)/g =(2 h)/(sin^(2) theta)`
and, horizontal range, `R =u^(2)/g sin 2 theta`
`=(2 h)/ sin ^(2) theta) 2 sin theta cos theta=4 h cat theta`
Thus the span of jump depends upon (i) heeight (h) attained or initial velcity or projection (ii) angle or grojection. theta`.
