A person standing on a road has to hold his umbrella at `60^(0)` with the verticcal to keep the rain away. He throws the umbrella an starts running at `20 ms^(-1)`. He finds that rain drops are hitting his head vertically. Find the speed of the rain drops with respect to (a) the road (b) the moving person.
