141891 A ball is dropped from height \(h\) and another from \(2 \mathrm{~h}\). The ratio of time taken by the two balls to reach ground is

141892 A body is falling freely from a point \(A\) at a certain height from the ground and passes through points \(B, C\) and \(D\) (vertically as shown below) so that \(\mathrm{BC}=\mathrm{CD}\). The time taken by the particle to move from \(B\) to \(C\) is 2 seconds and from \(C\) to \(D\) is 1 second. Time taken to move from \(A\) to \(B\) in seconds is

141893 A ball is thrown vertically upwards. It has a speed of \(10 \mathrm{~m} / \mathrm{s}\) when it has reached one half of its maximum height. How high does the ball rise? \(\mathrm{g}=10 \mathrm{~m}^{2}\)

141894 A ball is dropped from a height of \(19.6 \mathrm{~m}\). The distance covered by it in the last second is
