Question

An object is thrown between two tall buildings $180 m$ from each other. The object is thrown horizontally from a window $55 m$ above ground from one building through a window $10.9 m$ above ground in the other building. Find out the speed of projection. (use $g = 9.8$ $m / s^{2}$ )

Solution

The correct option is C $60 m / s$
$t = \sqrt{\frac{2 h}{g}} = \sqrt{\frac{2 \times 44.1}{9.8}}$
$t = 3 s$
$R = u T$
$\frac{180}{3}$ $= u; u = 60 m / s$
