The equation of motion of a projectile is $y=12 x-\frac{3}{4} x^2$ $..........\,m$ is the range of the projectile.
$12$
$16$
$20$
$24$
(b)
Put $y=0$,
$0=12 x-\frac{3}{4} x^2$
$x=16\,m$
A ball thrown by one player reaches the other in $2\, sec$. The maximum height attained by the ball above the point of projection will be about ………. $m$
A projectile crosses two walls of equal height $H$ symmetrically as shown The angle of projection of the projectile is
The initial speed of a projectile fired from ground is $u$. At the highest point during its motion, the speed of projectile is $\frac{\sqrt{3}}{2} u$. The time of flight of the projectile is:
