Question

Rain is falling vertically with a velocity of \(3 ~km/hr\). A man walks in the rain with a velocity of \(4~ km/hr\). The raindrops will fall on the man with a velocity (in \(~km/h\) ) of

Answer 1

Given,
\(v_r=3 ~km/hr\\
v_m=4 km/ℎr\\
\overrightarrow{v} _r/m=\overrightarrow{v} _r−\overrightarrow{v} _m\\
=3\hat{j} −4\hat{i} \\
v_r/m=
5 km/hr\)
