Question

A man standing on a road has to hold his umbrella at 37° with vertical to keep the rain away. He throws the umbrella and starts running at 12 km/h. He finds that rain drops are falling on his head vertically. Find the speed ( in km/hr) of raindrops w.r.t the moving man

Answer 1

Explanation:

Given A man standing on a road has to hold his umbrella at 37° with vertical to keep the rain away. He throws the umbrella and starts running at 12 km/h. He finds that rain drops are falling on his head vertically. Find the speed ( in km/hr) of raindrops w.r.t the moving man

• So velocity of the man is 12 km/h
• We need to find the speed of raindrops with respect to the moving man.
• So we have theta = 37 degree
• So in a triangle ABC we get
•             AB = BC / tan 37
•             AB = 12 / 0.75355
•              AB = 15.92 km/h
• Therefore the speed of raindrops with respect to moving man is 15.92 km/h
