What is the acceleration of a projectile at the top of its trajectory?

A stone is launched upward at 45^(@) with speed v_(0) . A bee follow the trajectory of the stone at a constant speed equal to the initial speed of the stone. (a) Find the radius of curvature at the top point of the trajectory. (b) What is the acceleration of the bee at the top point of the trajectory? For the stone, neglect the air resistance.

The ratio of the speed of a projectile at the point of projection to the speed at the top of its trajectory is x. The angle of projection with the horizontal is

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A: Path of a projectile with respect of another projectile is straight line . R : Acceleration of a projectile with respect to another projectile is zero.

A javelin thrown into air at an angle with the horizontal has a range of 200 m. If the time of flight is 5 second, then the horizontal component of velocity of the projectile at the highest point of the trajectory is

Acceleration of a particle under projectile motion at the highest point of its trajectory is :

A projectile fired from the ground follows a parabolic path. The speed of the projectile is minimum at the top of its path.

A projectile fired from the ground follows a parabolic path. The speed of the projectile is minimum at the top of its path.
