269776 The splash of sound was heard\(5.35 \mathrm{~s}\) after dropping a stone into a well \(122.5 \mathrm{~m}\) deep. Velocity of sound in air is

269778 A stone projected upwards with a velocity ' \(u\) ' reaches two points ' \(P\) ' and ' \(Q\) ' separated by a distance ' \(h\) ' with velocities \(u / 2\) and \(u / 3\). The maximum height reached by it is

269779 A ballis dropped from the top of a building. The ball takes \(0.5 \mathrm{~s}\) to fall past the \(3 \mathrm{~m}\) length of a window at certain distancefrom the top of the building. Speed of the ball as it crosses the top edge of the window is \(\left(\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}\right)\)
