A swan is flying at a speed of 17.5m/s. There is wind blowing from the East at 12.5m/s. a) If the swan pointed due South, what would be the magnitude and direction of its velocity relative to the ground?
b) If the swan wishes to travel south, what would be the magnitude and direction of its velocity relative to the ground?
c) If the swan travels due South as in part b, what will be its displacement after 8.5 hours?

the maxium height is 34m/s

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
