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 direction of velocity and acceleration of a projectile at the highest point on the trajectory are

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

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

If theta is the angle between the velocity and acceleration of a projectile at a point of its path, its value when the projectile is at the highest point is :
