141864 A ball is dropped from the top of a tower of height \(100 \mathrm{~m}\) and at the same time another ball is projected vertically upwards from ground with a velocity \(25 \mathrm{~ms}^{-1}\). Then, the distance from the top of the tower, at which the two balls meet is

141865 Two balls are dropped to the ground from different heights. One ball is dropped \(2 \mathrm{~s}\) after the other but they both strike the ground at the same time. If the first ball takes \(5 \mathrm{~s}\) to reach the ground. Then the difference in initial heights is \(\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)\)

141866 An aeroplane is flying horizontally with a velocity of \(600 \mathrm{~km} / \mathrm{h}\) and at a height of \(1960 \mathrm{~m}\). When it is vertically above a point \(A\) on the ground a bomb is released from it. The bomb strikes the ground at point \(B\). The distance \(A B\) is:

141867 Two bodies of different masses are dropped from heights of \(16 \mathrm{~m}\) and \(25 \mathrm{~m}\) respectively. The ratio of the time taken by them to reach the ground is:
