If we can throw a ball upto a maximum height $H$, the maximum horizontal distance to which we can throw it is
$2\,H$
$\sqrt 2 \,H$
$H$
$\frac{H}{2}$
If a stone is to hit at a point which is at a distance $d$ away and at a height $h$ above the point from where the stone starts, then what is the value of initial speed $u$ if the stone is launched at an angle $\theta $ ?
The ceiling of a long hall is $25\; m$ high. What is the maximum horizontal distance that a ball thrown with a speed of $40\; m/ s$ can go without hitting the ceiling of the hall ?
The horizontal range is four times the maximum height attained by a projectile. The angle of projection is ......... $^o$
