Question

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 which water is reaching. This 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.
