A stone thrown horizontally from the top of a vertical ice is completely melted. Determine the total mass of wall with a velocity of 15ms\(^{-1}\), hits the horizontal ground water in the container at a point 45m from the base of the wall. Calculate the specific latent heat of steam = 2.3 x 10\(^3\) Jg\(^{-1}\) height of the wall. [g = 10ms\(^{-2}\)]
Explanation
R = \(U\sqrt{\frac{2H}{g}}\)
H = \(\frac{gR^2}{2U^2} = \frac{10 \times 45^2}{2 \times 15^2}\)
