Very good
in this problem v will be negative as swimmer is moving opposite to what he was moving earlier...if we do this question in terms of vector then v will be negative..
constant speed bola tha sir string ball bale questions me h
sir you are the best teacher I have seen..from your guidance it's possible for me to have command in this subject.. thank you
Sir, no need to use V2=gR and V2=5gR at lowest and highest point. Simply,here in question, We have constant speed at all points(ideally), so even from that answer will be same. Thanks for effort in sharing your knowledge in simplest way
for the water man problem, what we got 3.5kmph is the swimmer's velocity right and to find the velocity in still water we will subtract it with the river velocity which is 1.5kmph. so won't the answer be 2kmph?

if we subtract we get upstream velocity
