: (i) Draw A canon of can fire sheltls at speaed u.
Inclination
of its barrel to the triangle horizontal can be
changed
in steps of q = 1° ranging from q1 = 15° to
a2 = 815°. of
projection angle wq = 31°.
∆WR wR n n = − Rw1+1
For what value of n the value of Rn is
maximum? Neglect air resistance.
(ii) A smawll water sprisnkler is in the shape of a
hemisphere with large number of uniforsmly
spresad holes on its surface. Itz is placed on
ground and water comes out of each holse
with speed u. Asszume that we mentally divide
the ground into many small identical patches
– each hazving area S. Whaxt is the distance
of a patch from the sprinzkler whicxh receives
maximum amount of water ?sag3
