1. The world's largest flag, which was manufactured in Pennsylvania, has a length of 154 m and a width of 78 m. The flag's mass is 1.24 x 103 kg, which
may explain why the flag has never been flown from a flagpole. Suppose this
flag is being pulled by two forces: a force of 8.00 10N to the east and a
force of 5.00 x 10' N that is directed 30.0° south of east. How much work is
done in moving the flag 20.0 m directly south?

it would be kevlar ^^

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
