A ball is thrown upwards and it returns to ground describing a parabolic path. Which of the following remains constant
At the top of the trajectory of a projectile, the directions of its velocity and acceleration are
An object is thrown along a direction inclined at an angle of ${45^o}$ with the horizontal direction. The horizontal range of the particle is equal to
The height $y$ and the distance $x$ along the horizontal plane of a projectile on a certain planet (with no surrounding atmosphere) are given by $y = (8t - 5{t^2})$ meter and $x = 6t$ meter, where $t$ is in second. The velocity with which the projectile is projected is
The range of a particle when launched at an angle of ${15^o}$ with the horizontal is 1.5 km. What is the range of the projectile when launched at an angle of ${45^o}$ to the horizontal
A cricketer hits a ball with a velocity $25\,\,m/s$ at ${60^o}$ above the horizontal. How far above the ground it passes over a fielder 50 $m$ from the bat (assume the ball is struck very close to the ground)
A stone is projected from the ground with velocity $25\,m/s$. Two seconds later, it just clears a wall 5 m high. The angle of projection of the stone is $(g = 10m/{\sec ^2})$
Galileo writes that for angles of projection of a projectile at angles $(45 + \theta )$ and $(45 - \theta )$, the horizontal ranges described by the projectile are in the ratio of (if $\theta \le 45)$
A projectile thrown with a speed $v$ at an angle $\theta $ has a range $R$ on the surface of earth. For same $v$ and $\theta $, its range on the surface of moon will be
The greatest height to which a man can throw a stone is $\sqrt {\frac{F}{{m\,r}}} $. The greatest distance to which he can throw it, will be
