Motion Under Gravity

If a ball is thrown vertically upwards with speed u, the distance covered during the last t seconds of its ascent is

Show answer and solution

Answer: (b)

  1. By symmetry, the last tt seconds of ascent mirror the first tt seconds of a fall from rest at the top.
  2. Distance =12gt2= \frac{1}{2}gt^2, independent of uu.
  3. So the answer is (b) 12gt2\frac{1}{2}gt^2.
