Question

a man walking with 3m/s feels the rain falling vertically with a speed of 4m/s. find the angle which the rainfall makes with the vertical according to a stationary observer.​

Answer 1

Hey Dear,

◆ Answer -

θ = 53.13°

● Explanation -

# Given -

vr = 3 m/s

vm = 4 m/s

# Solution -

Velocity of man (horizontal) and velocity of rain (vertical) make right angle with each other -

tanθ = vm / vr

tanθ = 4 / 3

θ = taninv(4/3)

θ = 53.13°

Therefore, the rainfall makes angle of 53.13° with the vertical according to a stationary observer.

Hope this is helpful..
