Let the object be thrown vertically upwards with an initial velocity‘u‘. if it rises to the maximum height‘h‘ in time‘t‘.Ascent (upwards)v = u + ator, v = u + (-a)tor, 0 = u – ator, t =^{u}/_{a – (i)}Descent (downwards)v = u +at_{2}or, v = 0 + at_{2}or, v = at_{2}or, t_{2 = v/}_{a – (ii)}As velocity at the time of descent ‘v’ is same as the velocity at the time of ascent ‘u’from (i) and (ii)t_{1 = t}_{2}so, Time of ascent = Time of descent (proved)
