Take a plastic pipe and fix a jet at one of its end. connect the pipe to a water tap attached to

a large overhead tank. fix a large protractor as shown in the figure so that you can hold the

pipe at different angles (say at 15 degree
, 30 degree
, 45 degree
and 60 degree
).

hold the pipe in such a manner that jet of water comes out at an angle of 15 degree
. measure the

distance up to water is . is the range of the projectile.

now hold the pipe at an angle of 30 degree
, 45 degree
and 60 degree
. measure the range of the projectile in each

case. keep the speed of water coming out of the jet same in each case.

what do you find? for a given speed, the range is maximum when the angle of projection is

45 degree
.

also, try to find out the effect of initial speed of water on the range of the projectile.
