Given information
From the question we can find the following values:
Rain drop's speed
Pan's cross-sectional area =
Water's density=
Rain falling rate =
Step-by-step explanation
Step 1.
When the raindrop collides with the pan's surface it loses all its momentum and transfers it to the surface
Hence the total force experienced by the surface as a result of momentum transfer from raindrops contacting the surface is given by
=the force
=the change in momentum
is the time interval,
= the velocity,
= the mass,
= the area,
= density.
=the change in height.
