A particle is projected from the origin in such a way that it passes through a given point P (a, b} What is the minimum requrired speed to do so?

A particle is projected from origin with speed u . Find the minimum value of u if the particle passes through a poiny P (a, sqrt(3)a) .

A particle is projected with a given velocity in two possible ways so as to make it pass through a point at a distant from the point of projection.Obtain a relation for the product of times taken to reach the point in the two possible ways.

A particle is projected with an angle of projection theta to the horizontal line passing through the points (P,Q) and (Q,P) referred to horizontal and vertical axes (can be treated as X-axis and Y-axis respectively). The angle of projection can be given by
