A man moving in rain holds his unbrella inclined to the vertical even though the rain drops are falling vertically downwards . Why ?

Text Solution

AI Generated Solution

To understand why a man moving in the rain holds his umbrella inclined to the vertical, even though the raindrops are falling vertically downwards, we can analyze the situation using vector components. ### Step-by-Step Solution: 1. **Identify the Velocities**: - Let \( v_m \) be the velocity of the man moving horizontally. - Let \( v_r \) be the velocity of the rain falling vertically downwards. ...

A man moving with a velocity of 5m//s on a horizontal road observes that raindrops fall at an angle of 45^(@) with the vertical. When he moves with a velocity of 16m//s along an inclined plane, which is inclined at 30^(@) with the horizontal , he observes raindrops falling vertically downward as shown in the figure. Find the actual velocity of the raindrops.

When a boy is stationary, he observes that rain drops are falling at 30^(@) to vertical direction. When he starts running with speed 10m/s , he observed that rain drops are falling vertically downwards. Calculate the actual velocity of rain drops.
