Choose the correct alternative $(s)$
If the greatest height to which a man can throw a stone is $h,$ then the greatest horizontal distance upto which he can throw the stone is $2h$.
The angle of projection for a projectile motion whose range $R$ is n times the maximum height is $\,\,tan^{-1} (4/n)$
The time of flight $T$ and the horizontal range $R$ of a projectile are connected by the equation $gT^2 = 2Rtan\theta$ where $\theta$ is the angle of projection.
All of the above
A truck is moving on the horizontal road with constant speed $v.$ A ball is thrown from the truck vertical up at speed $u$ $w.r.t.$ truck. What is distance traversed by the truck when ball returns on the truck
A bullet fired at an angle of $30^o$ with the horizontal hits the ground $3.0\; km$ away. By adjusting its angle of projection, can one hope to hit a target $5.0\; km$ away ? Assume the muzzle speed to be fixed, and neglect air resistance.
Aball is thrown from a point on ground at some angle of projection. At the same time a bird starts from a point directly above this point of projection at a height $h$ horizontally with speed $u$. Given that in its flight ball just touches the bird at one point. Find the distance on ground where ball strikes
In projectile motion, the modulus of rate of change of velocity
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:
