If a ball is thrown vertically upwards with a speed u the distance covered during last t seconds of its ascent
Answered by admin @
Let body takes T sec to reach maximum height.
Then v = u - gT
v = 0, at highest point.
T=u/g ………… (1)
Velocity attained by Body in (T - t) sec v = u - g (T -t)
= u-gT + zt = u-g u/g + gt
or v = gt …………. (2)
Distance travelled in last t sec of its ascent
S = (gt)t -1/2 gt2 = 1/2 gt2
