269981 A body is projected horizontally from the top of a tower with a velocity of \(10 \mathrm{~m} / \mathrm{s}\). If it hits the ground at an angle \(45^{\circ}\), the vertical component of velocity when it hits ground in \(\mathbf{m} / \mathbf{s}\) is

269982 A body is projected with an angle \(\theta\). The maximum height reached is \(h\). If the time of flight is \(4 \mathrm{sec}\) and \(g=10 \mathrm{~m} / \mathrm{s}^{2}\), then the value of \(h\) is \(\quad(2014-M)\)

269983 A person reaches a point directly opposite on the other bank of a river. The velocity of the water in the river is \(4 \mathrm{~m} / \mathrm{s}\) and the velocity of the person in still water is \(5 \mathrm{~m} / \mathrm{s}\). If the width of the river is \(84.6 \mathrm{~m}\), time taken to cross the river in seconds is ( \(2013-\mathrm{M}\) )
