A man standing on a road has to hold his umbrella at 37°with the vertical to keep the rain away. He throws theumbrella and starts running at 12 km/h. He finds thatraindrops are hitting his head vertically. Find the speed (inkm/hr) of raindrops with resepect to the moving man.

Answer»

When the man is at rest w.r.t. the ground, the rain comes to him at an angle 37° with the vertical. This is the direction of the velocity of raindrops with respect to the ground. Here v→rg=velocity of rain with respect to the ground v→mg= velocity of the man with respect to the ground. and v→rm=velocity of the rain with respect to the man, We have v→rg=v→rm+v→mg ......(i) Taking horizontal components equation (i) gives vrgsin37∘=vmg3/5

can you please explain it in detail
