Solution

(c) the kinetic energies of all the particles arriving at a given point are the same
(d) the momenta of all the particles arriving at a given point are the same

In a streamline flow, every fluid particle arriving at a given point has the same velocity v. Thus, the kinetic energies ( $\frac{1}{2} m v^{2}$ ) and momenta (mv) of all particles arriving at a given point are the same, as the mass of a particle is constant.

A particle is projected from point A on the ground at an angle $θ$ with horizontal. Another particle is projected from point B simultaneously from height 4H above point A with same velocity. A and B are in the same vertical plane, where H is the maximum height attained by the particle A. Both the particles collide at the same time on the ground. Find the angle at which particle B is projected with horizontal:
