A stone is projected from a point on the ground in such a direction so as to hit a bird on the top of a telegraph post of height h ,
and then attain a height 2 h above the ground. If ,
at the instant of projection ,
find the ratio of the horizontal velocities of the bird and the stone if the stone still hits the bird. ,
the bird were to fly away horizontal with a uniform speed ,
A projectile is fired with velocity v0 from a gun adjusted for a maximum range. It passes through two points P and Q whose heights above the horizontal are h each. Show that the separation of the two points is v0 /g
