The horizontal range and maximum height attained by a projectile are $R$ and $H$, respectively. If a constant horizontal acceleration $a=g / 4$ is imparted to the projectile due to wind, then its horizontal range and maximum height will be
$(R+H), \frac{H}{2}$
$\left(R+\frac{H}{2}\right), 2 H$
$( R +2 H ), H$
$(R+H), H$
At what point of a projectile motion acceleration and velocity are perpendicular to each other
A ball is thrown at an angle $\theta $ and another ball is thrown at an angle $(90^o -\theta )$ with the horizontal from the same point with same speed $40\,ms^{-1}$. The second ball reaches $50\,m$ higher than the first ball. Find their individual heights?
The equation of motion of a projectile is $y=12 x-\frac{3}{4} x^2$ $..........\,m$ is the range of the projectile.
Two projectile thrown at $30^{\circ}$ and $45^{\circ}$ with the horizontal respectively, reach the maximum height in same time. The ratio of their initial velocities is
If the range of a gun which fires a shell with muzzle speed $V$ is $R$, then the angle of elevation of the gun is
