Rain seems to be falling vertically to a person sitting in a bus which is moving uniformly eastwards with 10 m/s. It appears to come from vertical at a velocity 20 m/s. Find the speed of rain drops with respect to ground.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION
m/s
Sol. V RM = V R – V M
V R = V Rb + V b = 20 
+ 10 
tan θ = 
= 
|V r | = 
= 
m/s
making angle tan –1 
with vertical.
Ans. 
m/s
