man is walking on a horizontal road at velocity of 5 kilometre per hour and the rain appears to be falling vertically at 5 kilometre per hour to him. the magnitude of velocity of rain with respect to the ground is

Explanation:

=0km/h=0m/s

=5km/h=1.4 m/s

=5km/h=1.4m/s

relative velocity of rain with respect to ground

=+

=1.4+0

=1.4m/s

i need the answer to this too but idk it ; -;

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
