A particle is projected under gravity with velocity `sqrt(2ag)` from a point at a height h above the level plane at an angle `theta` to it. The maximum range R on the grond is :

A particle in projected with velocity sqrt(3gL) at point A (lowest point of the circle) in the vertical plane. Find the maximum height about horizontal level of point A if the string slacks at the point B as shown in figure.

A particle is projected from the ground with velocity u making an angle theta with the horizontal. At half of its maximum heights,
