At what point of a projectile motion acceleration and velocity are perpendicular to each other
At the point of projection
At the point of drop
At the topmost point
Any where in between the point of projection and topmost point
A missile is fired for maximum range at your town from a place $100\, km$ away from you. If the missile is first detected at its half way point, how much warning time will you have ? (Take $g = 10\, m/s ^2$) the maximum height of the missile is
If the time of flight of a bullet over a horizontal range $R$ is $T$, then the angle of projection with horizontal is ......
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
A projectile cover double range as compare to its maximum height attained. The angle of projection is
At the top of the trajectory of a projectile, the directions of its velocity and acceleration are
