361929 A child stands on the edge of the cliff \(10\;m\) above the ground and throws a stone horizontally with an initial speed of \(5\;m{s^{ - 1}}\). Neglecting the air resistance, the speed with which the stone hits the ground will be ____ \(m\,{s^{ - 1}}\). (Given, \(g = 10\;m{s^{ - 2}}\))

361930 A stone is to be projected horizontally from top of a \(1.7\,m\) high pole. Calculate initial velocity of projection (in \({{ms}^{-1}}\)), if it strikes perpendicularly an inclined plane as shown in the figure.

361931 A body of mass \(m\) is projected horizontally with a velocity \(v\) from the top of a tower of height \(h\) and it reaches the ground at a distance \(x\) from the foot of the tower, if a second body of mass 2\(m\) is projected horizontally from the top of a tower of height 2\(h\), it reaches the ground at a distance 2\(x\) from the foot of the tower. The horizontal velocity of the second body is :
